Description

Advantages

LW ST/HE

Medium-temperature

brine solution

Implementation of new control algorithms and redesigned

evaporator to allow chilled brine solution production down

to -6°C when ethylene glycol is used (-3°C with propylene

glycol)

Covers specific applications such as ice storage and industrial

processes

Only sizes :

1328/1528/2628/3008

Low-temperature

brine solution

Implementation of new control algorithms and redesigned

evaporator to allow chilled brine solution production

down to -12°C when ethylene glycol is used (-8°C with

propylene glycol)

Covers specific applications such as ice storage and industrial

processes

Only HE sizes :

1328/1528

Light-brine solution,

down to -3°C

Implementation of new control algorithms and redesigned

evaporator to allow chilled brine solution production down

to -3°C when ethylene glycol is used (0°C with propylene

glycol)

Matches with most application requirements for ground-sourced

heat pumps and fits with many industrial processes requirements

●

Unit supplied in two

assembled parts

The unit is equipped with flanges that allow disassembly

of the unit on site

Facilitates installation in plant rooms with limited access

Only sizes:

4228/4408/4608/4628

Evap. single pump

power/control circuit

Unit equipped with an electrical power and control circuit

for one pump evaporator side

Quick and easy installation: the control of fixed speed pumps is

embedded in the unit control

708-3428

230V electrical plug 230V AC power supply source provided with plug socket

and transformer (180 VA, 0,8 Amps)

Permits connection of a laptop or an electrical device during unit

commissioning or servicing

●

Evaporator with one

pass less

Evaporator with one pass on the water side. Evaporator

inlet and outlet on opposite sides.

Easy to install, depending on site. Reduced pressure drops

●

Master/slave

operation

Unit equipped with supplementary water outlet

temperature sensor kit (to be field installed) allowing

master/slave operation of two units connected in parallel

Optimised operation of two units connected in parrallel operation

with operating time equalisation

●

Condenser with one

pass less

Condenser with one pass on the water side. Condenser

inlet and outlet on opposite sides.

Easy to install, depending on site. Reduced pressure drops

●

21 bar evaporator

Reinforced evaporator for extension of the maximum

water-side service pressure to 21 bar (standard 10 bar)

Covers applications with a high water column evaporator side

(typically high buildings)

●

Single power

connection point

Unit power connection via one main supply connection

Quick and easy installation

2800/4628

21 bar condenser

Reinforced condenser for extension of the maximum

water-side service pressure to 21 bar (standard 10 bar)

Covers applications with a high water column condenser side

(typically high buildings)

●

Reversed

evaporator water

connections

Evaporator with reversed water inlet/outlet

Easy installation on sites with specific requirements

●

Reversed condenser

water connections

Condenser with reversed water inlet/outlet

Easy installation on sites with specific requirements

●

Condenser

insulation

Thermal condenser insulation

Minimizes thermal dispersions condenser side (key option for

heat pump or heat recovery applications)

●

Service valve set

Liquid line valve (evaporator inlet) and compressor

suction line valve

Allow isolation of various refrigerant circuit components for

simplified service and maintenance

●

Lon gateway

Bi-directional communication board complying with Lon

Talk protocol

Connects the unit by communication bus to a building

management system

●

Control for low cond.

temperature

Output signal (0-10 V) to control the condenser water

inlet valve

Simple installation: for applications with cold water at condenser

inlet (ex. ground-source, groundwater-source, superficial

water-source applications) the signal permits to control a 2 or

3-way valve to maintain condenser water temperature (and so

condensing pressure) at acceptable values

●

Compliance with

Swiss regulations

Additional tests on the water heat exchangers: supply

(additional of PED documents) supplementary certificates

and test certifications

Conformance with Swiss regulations
