Cleaning of Coolant side

In some applications, the fouling tendency can be very high, e.g.

when using extremely hard water at high temperatures. In such

cases, it is always possible to clean the Compact by:

Circulating a cleaning liquid (CIP - Cleaning In Place).

A solution of 5 % phosphoric acid or 5 % oxalic acid in water is

recommended to chemically clean the channels.

The flow rate of the cleaning liquid should be greater than the

design coolant flow, and it should flow in the reverse

direction through the heat exchanger compared to the

normal operation flow direction.

ATTENTION! After the cleaning process, it is very important that

the heat exchanger is flushed thoroughly with clean water before

start-up.

Cleaning of Gas side

Heavy condensation can have a self-cleaning effect, washing the

Compact and reducing fouling on the gas side. In applications

where the gas contains elements of soot, grease or oil residues

the risk of clogging the gas channel can be high. In such cases, it is

always possible to clean the Compact by:

Blocking the gas connections.

Circulating a cleaning liquid (CIP - Cleaning In Place) either

through the condensate connections or (if the fouling issue

have been addressed in the design phase) through specially

designed connections on the connecting pipes.

A suitable CIP-solution for the residues from the gas should

be used.

ATTENTION! Chemicals known to corrode copper (i.e. ammonia,

sulphur, etc.) are strictly forbidden to use as cleaning agent.

The flow rate of the cleaning liquid should be greater than the

design gas flow, and it should flow in the reverse direction

through the heat exchanger compared to the normal

operation flow direction.

ATTENTION! After the cleaning process it is very important that

the heat exchanger is flushed thoroughly with clean water before

start-up.

Warranty

Airec offers a 12-month warranty from the date of installation, but

in no case longer than 18 months from the date of delivery. The

warranty covers only manufacturing and material defects (poor

workmanship and/or faulty material). The warranty does not

cover damage caused by mechanical (including fatigue damage

due to vibrations/pulsations) and/or thermal stress.

The warranty does not cover damage caused by corrosion.

The warranty does not cover damages caused by dirt build up

and/or fouling.

load.

Storage

The Compact shall always be stored in a dry and protective

environment. The temperature should not be below 1°C and not

over 50°C for long term storage (more than 4 weeks).

At long operational stand-by periods the system should be

inspected for contamination on Liquid and Gas side, if necessary

clean the Compact according to the cleaning instructions. Liquid

side with water should be drained.

Disclaimer

The Compact

performance is based on installation, maintenance

and operating conditions done in conformance with this manual.

Airec cannot assume any liability for Compact heat exchangers

that do not meet these criteria.
