SRH

Swimming Pools Dehumidifiers

MTSRHGB

REV.072008

Microprocessors

All SRH units can be supplied with 2 kind of controls:

Basic control

;

it manages the following features: antifreeze protection, compressor timing, compressor automatic

starting sequence, defrost cycle, alarm reset, potential free contact for remote general alarm,

Advanced control

;

in addition to the basic control it manages a wider range of features as: setting the priority operation

mode (SRH/WZ only), managing of the main and the secondary set points, display of the alarms with
historical list, time band operation, integration with hot water coil and modulating valve. Upon request

the advanced control can be connected to a BMS system for the remote control and management. The

technical department is available to study, together with the customer, different solutions using

MODBUS; LONWORKS; BACNET or TREND protocols.

Electronic probe temperature-humidity

This sensor is supplied standard on the SRH/WZ versions supplied with advanced control.
It can be installed either in the room or in the return duct (to be specified before order) and allow the operation of the unit in the

following modes:

•

Dehumidification,

•

Heating ( by hot water coil),

•

Dehumidifi heating,

•

Dehumidifi heat recovery.

Control and protection devices

All units are supplied with the following control and protection devices: antifreeze protection sensor, high pressure switch with
manual reset, low pressure switch with automatic reset, high pressure safety valve, compressor thermal overload protection, fans

thermal overload protection.

Testing

All units are totally assembled and charged with refrigerant R407c. They are completely tested before the expedition. All units are in

accordance to the European Directives and they are provided of CE branding and relative conformity certificate.

OTHER VERSIONS

SRH/WZ Unit with heat recovery;

The unit is designed to have one refrigerant circuit condensed by air, the other one condensed both by water and air. If the unit is

supplied with the advanced control panel it is possible to set operation priorities (air or water).
In the SRH/WZ versions the heat recovery is designed to reject on the water about 50% of the total thermal load generated by the

unit. When the heat recovery is activated, the supply air temperature of the unit is, basically, the same of the return air, so,in this

case, the dehumidification is performed without air temperature increase. This operation mode is suitable during intermediate

seasons when the humidity in the swimming pool has to be controlled but also the room air temperature overheating has to be
avoided.

Low noise version (LS)

The low noise version LS is supplied with compressors jacket and complete acoustic insulation of the compressor vane with high
density sound absorbtion material.
