The Catalina Room Control Unit (RCU) is a heat exchanger and fresh air heat recovery system incorporating either LPHW heater battery or Electric elements (depending on the available heat / power source)
The unit measures 900 x 500 x 900 ideally located in a plant room/area and would be linked to the spa room and outdoors with 4 x 6M x 200mm flexible ducting and finished with louvered grilles. Additional ducting can be supplied.
The unit draws fresh air from the outdoors and passes this through a internal heat exchanger where it will receive the heat from the warm moist air being drawn from the spa room. The passing airs do not mix. The fresh, now warm air will pass through an internal heater where additional heat will be added if required before entering the spa room. The RCU is fully automatic controlling temperature and humidity and is variable speed.
The benefits of this system is that it provides fresh air ventilation, controls humidity, sets us a small pressure difference between spa room and house (to prevent moisture migration), fully conforms to building regulations, low running cost and minimal maintenance.
The RCU only uses 3amps to run (excluding and additional heat), it is almost silent in operation, and comes complete with its own temperature control and manual override. The RCU comes with 24M ducting, 4 louvered grilles, manual remote sited override switch, heater coil and zone valves and fitting instructions. 3 years full warranty.
Installation is straight forward and only requires a 3 amp single phase supply (larger if the unit is fitted with electrical coil heater) and a LPHW connection from a boiler and installing the 4 flexible ducts.
