KAPPA V ECHOS UNIT VERSIONS
KAPPA V ECHOS /HP: reverse cycle heat pump
In addition to the components of version KAPPA V ECHOS, this unit includes:
Refrigerant circuit: 4-way reversing valve, suction separator, liquid receiver, second thermostatic expansion valve.
Microprocessor enabled for summer/winter changeover and automatic defrost independently controlled for each
compressor, with a patented Blue Box logic, to obtain the maximum efficiency in the intervention and duration of
defrost cycles.
HYDRAULIC MODULE OPTIONSKAPPA V ECHOS 2PS: unit with storage tank and pumps.
In addition to the components of version KAPPA V ECHOS this unit includes:
insulated storage tank; run and standby circulating pumps, with automatic changeover by time or fault.
Expansion tank, check valves and gate valves.
Version ST is available in the following additional three configurations:
- ST 1PS: with 1 pump and a tank;
- ST 1P: with 1 pump without a tank.
- ST 2P: with 2 pumps without a tank
ACCESSORY VERSIONS
KAPPA V ECHOS /DC: unit with heat recovery condenser
In addition to the components of version KAPPA V ECHOS this unit includes, in each refrigerant circuit, a 100%
heat recovery brazed plate type condenser for the production of hot water and a liquid receiver. The recovery
condenser is a brazed plate type for models 16.1 and 32.2 and shell and tube for the remainder of the range.
The microprocessor automatically controls the water temperature and the high-pressure heat recovery safety
switch.
For the maximum efficiency of the device it is advisable to couple with fan speed control. Not available on HP
version.
