Calorex Delta

Calorex Delta

The new Calorex Delta Hybrid Fresh Air Dehumidification System supplied by Certikin International, is a breath of fresh air in environmental control systems. Fresh from commissioning one at Scarborough’s Crown Spa Hotel, Anthony Houfe of Pool Heat, Hull gives an honest appraisal of its installation.

Eager to reduce its energy consumption, the Crown Spa Hotel replaced a 14-year old Calorex Delta with a new 7-inch touch screen display Delta (Programmable Logic Controlled). The unit is controlled and adjusted on-site to match fan speeds precisely to ductwork resistance and automatically vary exhaust speeds to building load requirements. There are no hidden extras to consider – the new Delta is the full package.

Anthony says: “The new Delta heats the air and water efficiently and humidity is tightly controlled, verified by accessing the PLC logs. The site’s electrical consumption is greatly reduced by inverters controlling the fans and the water heats up even after a backwash. The new Delta has not only met, but surpassed our expectations.”

Spa Manager, Stuart Russell, says: “We’ve seen a marked improvement to the pool hall environment and pool water. It’s extremely economical and convenient to use. The support we’ve received from Pool Heat and Calorex has been excellent.”
