ACCESSORY VERSIONS
KAPPA V SR /DC: unit with heat recovery condenser.
In addition to the components of version KAPPA V SR this unit includes for each compressor a 100% heat
recovery condenser for the production of hot water. The microprocessor automatically controls the water tempe-
rature and the heat recovery safety switch.
KAPPA V SR /LN: low noise unit
In addition to the components of version KAPPA V SR this unit includes:
compressors located in a sound absorbing enclosure of painted galvanized steel, internally lined with sound
absorption material having an intermediate layer of high acoustic impedance material.
REFRIGERANT CIRCUIT ACCESSORIES:
- Desuperheaters
The desuperheater heat exchanger is arranged in series with the condensing coil. It is also available in a
heat pump configuration. In this case a shut-off valve must be fitted on the water recovery circuit, to be
closed during heat pump mode operation, as described in the manual.
- Pressure gauges.
Available on all models. Suction and discharge pressure values, read by transducers that relay the results to
the controller display, are already displayed as standard on all models.
