Description

Technical features

Split refrigeration systems featuring relative humidity control,
compossed by a condensing unit in low-noise or centrifugal construction
and an evaporating unit in a low-profile construction with double air
flow, oversized for high humidity refrigeration applications.

Controlled humidity preservation
The correct preservation of some goods, like fruits,
vegetables or flowers, requires to control the humidity
inside the cold room.
These split systems with humidity control are adjusted
for high humidity applications and they are specifically
recommended for positive temperature cold rooms for
horticultural products preservation.

•t 230V-I-50Hz or 400V-III-50Hz power supply.
•t Reduced R-404A or R-134A refrigerant load.
•t Hermetic reciprocating compressor.
•t High and low pressure switches.
•t Evaporador de plafón con doble flujo de aire dimensionado para una
regulación de humedad relativa del 60% al 95%*.

The evaporating units have double air flow trough oversized
coils to be able to get a relative humidity value inside the
cold room of about 95%, avoiding the loss of moisture and
weight from the product.

•t Inbuilt thermostatic expansion and solenoid valves in the evaporating
unit.
•t Air defrosting.
•t Stainless steel drain tray.
•t Flare-type cooling connections (up to 1/2”-3/4”) and service valves.
•t Magnetothermal protection.
•t Liquid receiver.

Temperature and humidity control

•t Refrigerant preloaded for 15 m pipe length.

The units feature an advanced electronic controller to
control both, temperature and humidity inside the cold
room.

•t Multifunctional electronic dual control for temperature and humidity,
and remote keyboard.

Relative humidity control with set point between
60% and 95%*,
Active humidification kits with water vapour addition
and dehumidification / heating kits are available as an
option.
* Control of relative humidity inside the cold room is
done in a passive way, by regulating the air flow of the
evaporating unit, without adding water vapour. The real
regulation range of relative humidity depends on the real
conditions of the cold rooms, ambient absolute humidity
and kind of product.

Maximum vertical distance between units of 15 metres in case the condensing unit is placed at a higher
place than the evaporating unit, and of 6 metres otherwise.

Electrical wiring
The following electrical wiring should be planned to
connect condensing and evaporating units (10 m long
connections are included in HSH series as standard).
