Electronic expansion valve (EXV)

The EXV has a stepper motor and a sight glass which can be used 

to check the mechanism movement and the presence of the liquid 

gasket.

11.6 - Moisture indicator

Located  on  the  EXV,  enables  control  of  the  unit  charge  and 

indicates moisture in the circuit.

The presence of bubbles in the sight glass indicates an insufficient 

charge or non-condensables in the system. 
The presence of moisture changes the colour of the indicator paper 

in the sight glass (from green to yellow).

11.7 - 

Dehumidifier filter

The role of the dehumidifier filter is to keep the circuit clean and 

moisture-free. 
The moisture indicator shows when it is necessary to change the 

element. 

A difference in temperature between the filter inlet and outlet shows 

that the element is dirty.

11.8 - 

Refrigerant accumulator with built-in 

filter drier

Specific data 30RQ/30RQP

The refrigerant charge required in cooling mode is greater than 

the permissible refrigerant charge in heating mode. The 

accumulator is used to store the excess charge in heating mode.

A removable element and metal filter keep the refrigerant circuit 

clean and free from moisture, by capturing solid contaminants.
When the moisture indicator turns yellow, it is necessary to change 

the element. When the unit is operating in cooling mode,  

a  difference  in  temperature  between  the  tank  inlet  and  outlet 

indicates fouling of the element and/or filter.

11.9 - 

Water type heat exchanger

The water type heat exchanger is a brazed plate heat exchanger 

with two refrigerant circuits.
The hydraulic connections of the heat exchanger are Victaulic 

connections.
The water type heat exchanger is thermally insulated with 19 mm 

of foam. 
As an option it can be protected against frost by an electric heater 

(water exchanger frost protection option).

Any products used for thermal insulation of recipients during 

hydraulic connection must be chemically neutral to the surfaces 

on which they are applied. All original materials supplied by the 

manufacturer comply with this requirement.

NOTE - Monitoring during operation

 

-

Follow local regulations on the monitoring of pressure 

equipment

 

-

The user or the operator is usually requested to create 

and maintain a monitoring and maintenance register. 

 

-

In the absence of any regulations, or in addition to the 

regulations, follow the guidance in the EN 378 standard.

 

-

Follow  the  local  professional  recommendations, 

whenever they exist.

 

-

Regularly check for the presence of any impurities  

(e.g.  sand,  grit)  in  the  heat-transfer  fluids.  These 

impurities maybe the cause of the wear or corrosion by 

puncture.

 

-

The reports of the periodical checks by the user or the 

operator  must  be  included  in  the  monitoring  and 

maintenance log. 

11.10 - Refrigerant

Units operating with R32 (A2L fluid).
Potentially flammable zones have been identified on the edge of 

the unit: please refer to chapter “4.4 - Positioning of potentially 

flammable zones around the unit”.

11.11 - 

High-pressure safety pressure switch

The units are equipped with high-pressure safety pressostats with 

automatic reset.
These pressure switches are located at the discharge of each 

circuit. 

11.12 - 

Variable frequency drive

30RBP and 30RQP units are equipped with variable frequency 

drives to control the fan speed within the fmin-fmax frequency 

range (standard, fmin=5 Hz and fmax=50 Hz). 

All fans on the same refrigerant circuit are actuated and controlled 

by a single variable frequency drive. The fan is driven by generating 

a supply waveform with a variable frequency and voltage, 

generated by pulse width modulation. 
Fan start-up/shut-down and the working range frequency setpoint 

are controlled by the Controller through RS485 communication 

using the LEN Protocol.
