Case Studies

Private pool Spalding

A private pool in Spalding required a new ventilation unit because the existing unit was unreliable and didn’t maintain the internal condition.  The client purchased the unit direct from Recotherm and carried out all the installation himself.

Pelican Centre

BACKGROUND:

Tudor North West Ltd a mechanical services contractor were approached by Wigan council when they had a problem with a noisy ventilation unit on a community swimming pool.

PROBLEM:

The existing unit was manufactured by Moducel Ltd and when originally installed had a run around coil system and a heat pump and operated on a full fresh air basis. The heat pump had been removed years before and now the unit was operating on full fresh air with a run-around coil heat recovery system.

The problem was that people in a new housing development close to the plant room were complaining about the noise from the unit, particularly at night in the summer, when they have open windows for ventilation whilst they are trying to sleep.

EVALUATION:

The main problem was that the existing unit was 6 meters long leaving no room to add attenuation, so the decision was taken to replace it. Tudor’s attitude was if you are going to the trouble of replacing the unit you might as well fit the most efficient unit on the market, so they approached Recotherm.

SOLUTION:

Recotherm designed a unit handling an air flow of 5 m3/s which incorporated the latest EC fans, recirculation facility and a high efficiency recuperator all in a length of 3470 mm. Thus allowing for the installation of attenuators which were 1500 mm long. The added bonus was that the unit could be supplied in flat packed form so there was no need to knock down and re build any walls.

BENEFITS:

The installation took a little over two weeks to finish and everybody is very pleased.

The locals are pleased because the noise has gone.

The council is pleased because the locals have stopped complaining.

The operator is pleased because the running costs have reduced

Tudor and Recotherm are pleased because they solved a difficult technical problem and helped their client solve a community issue.

Martin Killern of Recotherm commented

“Recotherm are leading innovators in swimming pool fresh air ventilation and have a unique problem solving mentality –  sometimes a standard package that looks value for money just doesn’t solve the problem. That’s why we offer a bespoke service to the industry.”

Unit A, Astwood Business Park

Astwood Lane, Astwood Bank, Redditch, Worcestershire, B96 6HH

Holiday Inn, Eastleigh

Due to the operational and reliability issues of the existing Dantherm unit the pool hall conditions could not be maintained in-line with criteria set by CIBSE.  The heat pump system was redundant offering no energy efficiency, the control system was non-operational, and the unit was running at a fixed high speed setting resulting in high energy consumption.

Recotherm were appointed to carry out the replacement of the swimming pool ventilation air handling unit.

Following the feasibility and design approvals the existing unit was isolated, made safe, and then stripped out and removed from site.

Recotherm provided a new ventilation unit in a flat pack form; this was constructed on-site, within the plantroom, eliminating the need for expensive builders works. Upon completion of the construction, the existing ducting was modified to suit the arrangement of the VFHE unit.

Modification to the LTHW pipework and electrical distribution were also carried out.

Completion of the installation followed with the set-up and commissioning of the new unit.  The pool hall internal environment is now extremely good and in-line with design intent.

Stourport Manor Hotel

BACKGROUND:

The Hallmark Hotel Stourport Manor have a spa leisure complex that was served by an old Heatstar air conditioning unit, which after 18 years service was no longer working correctly and was costing a lot of money to keep operational.  This affected the hotels ability to provide an optimal environment for guests in the leisure complex and from the maintenance engineers point of view was becoming increasingly difficult to maintain.

ASSESSING THE PROBLEM:

The increasing fallibility of the air conditioning unit meant that conditions in the pool hall had deteriorated over a period of time resulting in condensation on the windows and low temperatures in the pool hall. Thus both customer enjoyment and the structure of the building were deteriorating. The maintenance engineers felt that rather than to continue to spend money on the old unit the decision should be taken to get it replaced.

EVALUATION:

A number of companies were approached and Recotherm’s offer was chosen as being the best in terms of cost and technicality. The hotel liked the fact that Recotherm are swimming pool specialists who make one of the best units on the market and were also able to supply the unit in flat packed form, meaning that the old unit could be removed and a new unit installed without disturbing the structure of the building. Bringing the facility back on line quickly.

SOLUTION:

Recotherm supplied a model Aeris D which has been specifically designed as a replacement unit for both the Calorex Delta and Heatstar Phoenix units. Using this unit meant that the ductwork cost could be kept to a minimum.

BENEFITS:

A better environment in the pool hall.

State of the art controls including a touch screen display with temperature graphs, meaning greater control of temperature and humidity.

E spec fans mean quieter operation.

Lower running cost

Alan Broom, Maintenance Engineer, commented:

“We are very happy with the installation and would definitely recommend Recotherm to anyone else looking to replace their ventilation unit. The unit works great and we haven’t had a bead of condensation on any of the windows since it was installed.”

Martin Killen of Recotherm commented:

“This was a relatively easy installation for us and one we completed in 7 days. We are set up to provide solutions to these situations where old units are end of life and the customer needs a more reliable, cost effective solution with minimal disturbance in the transition. Our after sales service plan means that engineers like Alane can rely on this unit for years to come and dedicate their energies to more pressing matters.”

Blackbird Leys Project

BACKGROUND:

F.G. Alden Ltd of Oxford were awarded the contract to supply the mechanical and electrical services for the prestigious new Blackbird Leys swimming complex in Oxford. The new facility comprised a 25m main pool with moveable floor, a teaching pool, a toddlers’ splash pool, village and group changing facilities, spectator seating including café style area, a sauna, and a soft play area.

The new facility had a number of energy efficient and carbon reduction measures including a biomass boiler, combined heat and power unit, pool covers, and energy efficient plant and lighting. As part of the energy efficient plant, F.G. Alden have awarded the contract for the swimming pool environmental control ventilation units to Recotherm Ltd of Redditch.

F.G. Alden’s have been one of the country’s leading M&E services companies for over 85 years, working on some of the highest profile projects. They first worked with Recotherm over twenty years ago when Recotherm supplied the ventilation and environmental control unit for the prestigious Charterhouse School in Surrey.

PROBLEM:

In the original specification for the Blackbird Leys project, the environmental control units were to be from a German manufacturer. However, Alden’s got in touch with Recotherm and asked them to specify suitable units, as they knew with Recotherm there would be a significant saving in running costs, with no loss of air quality or performance; as well as better characteristics in meeting the energy-efficiency and carbon-reduction aims.

F.G. Alden also cited Recotherm’s exemplary post-sale service performance.

 

 

SOLUTION:

Recotherm supplied two of their high efficiency CVME 700 2HX units to serve the pool hall, and a CVME 400 2HX to serve the adjoining areas. All of the units have at their heart the dual pass recuperator (DPR) system, which can offer efficiencies of up to 90%. This is of vital importance because pool hall ventilation and environmental control were the most energy demanding drain on a leisure centre’s non-human resource operating costs.

In fact, the inclusion of Recotherm units, along with many other measures to increase energy-efficiency and reduce running costs and carbon-footprint, meant Oxford City Council expected to achieve a BREEAM (Building Research Establishment Environmental Assessment Methodology) ‘Very Good’ rating for the new pool (source oxford.gov.uk). BREEAM is the world’s foremost environmental assessment method and rating system for buildings, setting the standard for the best practice in sustainable building design.

BENEFITS:

David Hale, F.G. Alden’s contracts manager, said of their decision to specify Recotherm units “We were very happy to award the contract for the pool ventilation and environmental control equipment to Recotherm. Having worked with them on previous high profile projects, we have much experience of the quality, reliability and performance of their products; and we’re extremely confident that the Recotherm units specified will not only handle the demands placed on them in controlling the environment in the new facility at Blackbird Leys, but do so returning minimal running and service costs”.

Martin Killen, Recotherm’s managing director says of this latest feather in the company’s cap, “We’re delighted to work on the contract at Blackbird Leys. We know that by applying the latest cutting edge technologies we incorporate in our CVME units, we can meet the client’s needs, satisfy all the demands placed on the system, whilst reducing energy and service costs, and reduce levels of system noise”.

Edenbridge Leisure Centre

When Sevenoaks District Council took over the management of Edenbridge Leisure Centre in January 2001, after it had been under private management for 5 years, they were shocked to find that the air handling plant had fallen into disrepair due to a lack of maintenance. The problem was so acute that a decision was taken to replace the unit.

The main problem facing the council was that access to the plant room was limited. So when Recotherm advised that their state of the art fresh air ventilation unit could be constructed on-site they were delighted.

The whole project took 9 days to complete including removing the existing heat pump unit and modifying the ductwork to suit the new unit. Peter Kemp of Sevenoaks District Council commented that the unit had dramatically improved the internal conditions in the pool hall.

New Maldon Leisure Centre

The council were not happy with the performance of the existing unit and were concern how much it was costing to service. Recotherm were asked if it would be possible to replace the existing unit without having to disturb the building structure. The original unit was cut up and removed from site, the new unit was brought on site in flat pack form and assembled in position. After slight modifications to the existing ductwork and pipework systems the unit was commissioned and set to work. The whole project was completed in two weeks.

The cost of servicing the unit has been reduced to £400.00 per annum.


Southgate Leisure Centre

The Problem

The existing unit was forever breaking down and getting spare parts was not easy as the unit was constructed in Germany .The decision was taken to replace the units but the problem was how could they get the new unit in when the plant room was at the top of the building and the only access was through a standard door way.

The Solution

Recotherm provided the solution by bring there unit on site in flat pack form and building the unit on the site of the original unit. The fact that the construction had to accommodate two 6 inch heating mains that rose up through the centre of the unit didn’t pose a problem for Recotherm who simple constructed a bespoke unit to accommodate the pipes.

Oswestry Leisure Centre

The project was originally specified as an ESG system but the contractor, Technic Mechanical Services, were not happy with the information provided by ESG; so they asked Recotherm to look at the project and provide a price for a unit to supply air into both the pool hall and also serve the adjacent changing room.

In order to give separate temperature control for the pool hall and the changing room Recotherm designed a unit with twin heater batteries both controlled from separate three-port mixing valves. The price was accepted by the contactor and the projected was completed in the Summer of 2011.

Holgate Caravan Park, Silverdale

The existing unit was a Calorex HRD 15, handling 12,000 m3/h (3.33m3/s). The condition in the pool hall had not been right for two years and the owners had spent a lot of money trying to maintain the unit. They took the decision to replace the unit with another Calorex unit but, when they approached the consultant he told them about another site that had a Calorex unit replaced with a Recotherm unit two years earlier and were happy with the results.

This second site was Crowood Leisure Centre, Mike Holgate of Holgate Caravan Park visited Crowood, and there, took the decision to change his unit for a Recotherm unit because he was particularly impressed with the simplicity of the system. 

Holgate Holiday Park organised the removal of the existing unit and the installation of the new unit themselves. Recotherm delivered the unit on the Friday before work commenced and commissioned the unit the following Wednesday.
