TECHNICAL DATA

Each cooler is subjected to a pressure and a tightness test.

The cooler design is constantly being improved, so some models can slightly diﬀer from those ones described in this manual.

The duct coolers are designed for supply air cooling in supply or air handling units integrated into rectangular ventilation systems.

The cooler is a component part and is not designed for independent operation.

Transported air must not contain any ﬂammable or explosive mixtures, evaporation of chemicals, sticky substances, ﬁbrous materials,

coarse dust, soot and oil particles or environments favourable for the formation of hazardous substances (toxic substances, dust,

pathogenic germs).

Duct water cooler OKW (OKW1):

Maximum operating pressure: 1.5 MPa (15 bar).

Direct expansion cooler OKF (OKF1):

Maximum operating pressure: 2.8 MPa (28 bar).

DESIGN AND OPERATING PRINCIPLE

The cooler casing is made of polymer coated steel, the tube collectors are made of copper and the heat exchanger surface is made

of aluminium plates. The cooler casing has a dismountable design that provides easy access to the heat exchanger and the droplet

separator. The cooling coils are available in 3 rows modiﬁcation.

The internal operating medium of the OKF (OKF1) duct cooler is an evaporating refrigerant, i.e. R123, R134a, R152a, R404a, R407c, R410a,

R507, R12, R22.

The internal operating medium of the OKW (OKW1) duct cooler is water or antifreeze.

If necessary change the service side by turning the cooling coil through 180°. The OKF1 and OKW1 do not have this option. By default

the service side is on the right in the direction of the air ﬂow.

Service side change

To attain the maximum cooling capacity the cooler must be connected on counter-ﬂow basis

MOUNTING AND SETUP

The cooler is connected to the air duct with a ﬂange connection

Connection of the cooler to the air duct

Outdoor installation of the cooler is allowed only if the refrigerant is an antifreeze (ethylene glycol solution). During mounting consider

the operating characteristics of the mixing unit actuator.

While mounting the cooler provide quick and easy dismantling of the heat exchanger, the drain pan and the drain pipe.

• The cooler can be installed only horizontally to enable condensate drainage.

• While mounting the cooler provide enough access for servicing and repair operations.

• The duct cooler may be installed upstream and downstream of the ventilation unit. If the cooler is installed downstream of the fan,

provide at least 1-1.5 m air duct between the cooler and the fan for air ﬂow stabilization.

Prior to starting mounting check the tube, plates and the tube collector condition. Flanges of the system components are mounted with

galvanized bolts and M8 nuts.

For OKW1 and OKF1 the ﬂanges of the system components are mounted with galvanized bolts and M8 nuts, pre-installed in the cooler.

Prior to mounting remove the bolts and after the mounting screw them back.

Prior to starting operation and after a long downtime ﬁll the U-trap with water. Negative pressure coolers can be equipped with a U-trap

and a ball valve. Such U-trap must not be ﬁlled with water.
