All the chillers described in this manual work on the basis of the same principle. A refrigerant circuit cools the exchange
surface of an evaporator through which the liquid to be cooled passes.
The evaporator finds inside the tank.
The refrigerant compressor is controlled by an electronic control unit.
The electronic control unit controls the temperature of the water in the tank to maintain it within preset limits.

4.1.1

Refrigeration compressor

Of alternative hermetic type (TAEevo Tech MINI 02-03) and of rotary hermetic type (TAEevo Tech MINI 05-10), cooled by
the aspirated refrigerant and equipped with thermal cutout protection.
The compressor is mounted on anti-vibration supports.

4.1.2

Casing

Built with galvanised panels and painted with epoxy resins.
The panels have no structural function so that they can easily be removed to permit total access to all the components.

4.1.3

Materials in contact with the liquid to be cooled

Stainless steel, copper, brass, plastics, aluminium.

4.1.4

Condenser

Condensation occurs in finned core coils composed of copper tubes and headers, corrugated aluminium fins, and galvanized
sheet metal shoulders.

4.1.5

Evaporator

The evaporator is of the finned core type; water flows in contact with the finned surface at velocities such as to ensure low
pressure drops, while the refrigerant flows through the tubes.
In these models the exchanger is protected from the risk of ice formation caused by low evaporation temperatures, with anti-
freeze strategies handled by the electronic controller. The evaporator water outlet temperature is controlled by a probe. If
room/water temperatures lower than +5°C are required, a mixture of water and glycol must be used.
To drain the circuit use the appropriate discharge.

4.1.6

Pump

Of peripheric type, body in brass/bronze, impeller in brass, shaft in stainless steel.

NOTE

The pump must never run dry.

4.1.7

Accumulation tank

Plastic accumulation tanks are used.
These units are furnished with a tank, finding in vertical position over the unit’s base.
The tanks contain the evaporator.
The hydraulic circuit is of atmospherical type and by a plug, positioned on the top of the unit, it is possible to fill the unit.
A water level gauge is provided.

4.1.8

Fans

The fans are of axial type with ON/OFF operation.

4.1.9

Cabinet

The entire plinth, the uprights, and the outer panels are made of galvanized carbon steel sheet and are assembled by means of
screws and/or rivets. All panels undergo phosphor degreasing treatment followed by epoxy polyester power coating.
The frame is designed to allow easy access to all components of the unit.
