CMCH-3M : Compact modular water chiller 3-9 kW

This new compact modular cooling unit, made of stainless steel, is an ideal and flexible solution for small and medium-size breweries, cider makers and wineries, that only need cooling for their applications.
The modular cooling unit is also ideal solution for producers who are just starting up and who are planning to grow and expand their production capacity in the future. Particularly if they start operations in a small facility with available only 1-phase or limited 3-phase electric power network.
The unique feature of the modular cooling unit is its modular concept: The modular cooling unit can be optionally equipped with one, two or three cooling modules. Each module has a cooling capacity of 3 kW, so that the cooling machine can cover a performance range from 3 kW to 9 kW cooling capacity. The additional cooling modules up to full cooling capacity 9 kW can be ordered and added into the ready slot in the base unit at any time and very easily.
At 0°C water temperature an ice-bank will be built around the tubes which provides an additional, stored cooling capacity and enables a constant cooling temperature over a longer time. The modular cooling unit with one, two or three modules is able to cool water down to -6 °C using propylen glycol.

Designed and produced in Germany.

Why to purchase the modular cooling unit ?

• All in one plug and start system
• Refrigeration modules 3 kW connected with a quick plug system
• Easily expandable from 3 kW to 6 kW or 9 kW of the cooling capacity
• No technician is needed for the exchange of the cooling modules
• Exchange of the modules possible during operation
• Internal cold water pump
• The pump can be switched off by pressure switch
• Dry run protection (shown by led)
• Open buffer tank 87L (stainless steel)
• Overflow protection kit is available as an optional accessory
• Three available cooling capacity’s in one cooling unit
• Ice accumulation bank for load peaks

Applications

• Passive cooling of fermentation and storage tanks
• Cooling of beer, cider, must and wine down up to -6°C
• Cooling of rooms and storage halls – with additional fans
• Biological reduction of acids
• Wine stabilization
• Regulation of fermentation temperature
• Cool storage of wine until bottling

Technical parameters :

• Digital thermostatic controller
• Complete cooling water circuit containing an open water tank
  and a pump
• Cooling capacity … it depends on number of the cooling modules, temperature of cooling media and ambient temperature – see the table bellow
• Ecological refrigerant gas … R290 (150g per each cooling module)
• The pump can be switched on / off manually or automatically switch-off the pump by pressure switch when valves are closed
• Every cooling module consists of a stainless steel evaporator, a compressor and a condenser.
• All parts in contact with the water or glycol in the cooling unit are insulated.
• Buffer tank capacity … 80 liters
• Electrical connection … 1-phase 220-240V/50Hz/16A  or 3-phase 380-420V/50Hz/16A (according to ordered version)
• Cooling medium … water / monopropylen glycol
• Cooling water (glycol) temperature from approx. -6° to +15°C
• The ice-bank arises at 0°C water temperature.
• It is required to add monopropylen glycol (30 – 35%) to the cooling water by outlet temperatures below 0°C. In this case the building of an ice-bank not possible.
• Maximal ambient air temperature 32°C
• Integrated pump Ebara
• Fittings for cooling media hoses output / input … 2x  3/4” AG (male)
• Dimensions (L x W x H) : 1020 x 580 x 720 mm
• Weight : 205 kg (empty)

… and other technical parameters. The values are valid for ambient temperature max. +32°c

Optional accessories :

I. CMCH-CM30 : Cooling module 3 kW for the CMCH modular water chiller

Cooling module with cooling capacity of 3 kW for the compact modular water chiller 3-9 kW. The cooling module includes the R290 ecological refrigerant gas 150g.
The cooling module consists of a stainless steel evaporator, a compressor and a condenser.

II. CMCH-OFP : Overflow protection kit for the CMCH modular water chiller

The ‘Overflow protection kit’ prevents residual water from the pipes of open water-systems to over-flood the cooling unit’s integrated water-tank when the pumps are switched off.

Overflow prevention-kit comprised of a solenoid valve with connection and a non-return valve, recommended for installations where water pipes or tanks stand higher than the unit.

III. CWC-CMC Compact manifolds

The hose-hub to connect more cooling zones on cooled tanks to this cooling unit using flexible plastic pipes or hoses.
