DEHUMIDIFICATION

Featuring a streamlined user interface, the control system on the popular Calorex Delta has undergone some major improvements, making it even more user friendly

Golden Coast Managing Director Jamie Adams explained: “At Golden Coast, we understand that our success is only possible through yours. So wherever you are in the process – whether you’re specifying, installing or even servicing – we will do our best to give you the technical support you need to get the job done as efficiently as possible.”

TAP AWAY TO AN IMPROVED DELTA CONTROL PANEL Featuring a streamlined user interface, the control system on the popular Calorex Delta has undergone some major improvements, making this swimming pool environmental control unit even more user friendly. Available through the heating and ventilation division of Certikin International, Calorex Delta’s provide hard to beat environmental control system with a comprehensive range to suit pools of every size. These systems are specifically designed to economically provide the environmental comfort and moisture related structural protection necessary for a pool. The popularity of the Delta continues to grow, with the touchscreen control panel giving Calorex customers a more flexible approach to system management that allows various functions of the unit to be controlled more closely, plus many standard features that were previously optional extras.

But now Calorex have made some further enhancements to its controls, which gives customers some further upgrades such as sleeker graphics, BACnet connectivity for BMS and an additional sensor for improved LPHW frost protection in cold climates. As standard, the Calorex Delta has screen mirroring capabilities to Android and iOS mobile devices using a third-party app, and to a web browser with ActiveX, while Modbus and BACnet connectivity offer extensive options for BMS interfacing. In addition to the redesigned user interface, one of the major improvements with these upgrades is the additional sensor to improve frost protection. The extra sensor measures LPHW temperature leaving the Delta, and combined with the fresh air temperature sensor, provides accurate frost protection in cold conditions. “We believe that these upgrades are an important addition to customer experience and demonstrates Calorex’s continued commitment to remain the flag bearing manufacturer of purpose designed swimming pool environmental control systems,” said Lee Austin, Head of UK Operations and Group Engineering at Calorex. The upgraded control system is now available with all new Delta machines.

A BREATH OF FRESH AIR FROM RECOTHERM The swimming pool environment is one of the most challenging environments for a ventilation engineer to design. Fundamentally the system needs to balance the comfort of bathers with the protection of the building structure and to achieve this there are two main options available – heat pump refrigerant based systems or fresh air systems. The term ‘heat pump’ in connection with dehumidification is somewhat misleading as a heat pump is not a dehumidifier and vice versa. According to industry innovators Recotherm, systems which utilise this technology have a number of shortcomings including worse than expected efficiency, corrosion and maintenance issues plus the re-circulation of the pool hall atmosphere. Recotherm have therefore opted for solutions featuring the fresh air option and with over 30 years’ experience of pool environment control, they produce a range of systems which avoid these shortcomings whilst delivering lower running costs. In principle, these systems work on the basis that throughout the year, fresh air has lower moisture content than the air inside a pool hall. By introducing fresh air, it will lower the moisture content of the atmosphere and thus the relative humidity within the pool hall. It’s a straightforward concept but you can’t just open a window and that’s it. To do the job economically you need

‘controlled fresh air’ otherwise running costs would actually be high. What is needed is to introduce the precise amount of fresh air that is required and no more. Recotherm’s fresh air solutions combine a number of energy saving techniques to reduce the overall energy bill and these include heat recovery systems, variable speed EC fans and building management control units. Each plays an essential part in the overall system and typically a fresh air unit runs at 60% of the cost of a refrigerated unit. At the same time it protects the building fabric better, completely removes stale air and odours plus it can last for over 20 years if maintained properly. With a UK based manufacturing centre combined with in-house design, Recotherm can cater for virtually any need and all systems are backed by full service and maintenance teams.

HEATSTAR – HELPING BEAT THE PROBLEMS OF POOL HALL HUMIDITY With advances in technology, pool dehumidification is now just one part of the environmental control required for today’s indoor swimming pools. The key elements in pool environmental control include dehumidification, ventilation, air quality, air heating and pool water heating. However, in today’s environmentally Recotherm’s fresh air solutions combine a number of energy saving techniques including heat recovery systems, variable speed EC fans and building management control units
