Danfoss Selection of ICF made easy - Save even more time with this revolutionary valve train that combines the functionality of a conventional valve station into a single compact unit. It features quick installation with only two welds, faster service due to its unique design, and is applicable to various non-flammable refrigerants.

Quick Selection Guide

50%

The ICF valve stations are

designed to quickly and

eciently evacuate refrigerant

during service calls so you can

get your product COOL.

80%

less installation time

Keep productivity up by making

two welds instead of 10 or more.

Experience better functionality

while lowering pressure drops.

less service time

Selection of ICF made easy

Save even more time with ICF

ICF stands for valve trains and for over ve years installation and service has never been easier. This

quick guide provides you with key information to choose the right ICF in common applications such as

pumped liquid, hot gas and liquid injection lines.

Applicable to all common non ammable

refrigerants including R717, R744 (CO

) and non

corrosive gases/liquids dependent on sealing

material compatibility.

For further information please refer to installation

instruction for ICF.

Use of the ICF control solution with ammable

hydrocarbons is not recommended.

For further information please contact the local

Danfoss sales company.

If the ICM module is going to be used in liquid

refrigerant with a temperature above +75°C

(+167°F), please contact Danfoss.

The valve train of the

Future since 2005

The ICF valve station is an innovative solution that

provides the full functionality of a conventional

valve station in a single compact unit.

Eliminate project bottleneck:

Conventional valve stations of six or more

individual components and up to twelve welds.

ICF means two welds directly at the job site

Down time during service is reduced to a fraction

compared to conventional valve trains.

The unique design of the ICF ensures a quick

pump down and faster access to valve modules.

The ICF valve is a compact valve train ready for

the jobsite.

This solution provides you with a variety of

benets:

Designed for Industrial Refrigeration

Supplied fully assembled. No need to

disassembly prior to installation under normal

welding procedures

Standard side ports to t service valves,

pressure transmitters, sight glasses.

Applicable to all common non ammable

refrigerants including R744 and R717.

Direct Weld Connections (No leaks through

anges)

Compact design, faster service

Available with dierent connection types

including ANSI and DIN, Socket weld

High capacities low pressure drop

Low weight design

Liquid injection

to separator

(Liquid make up)

The ICF valve station oers a unique solution for

liquid injection to separator. For this application

the ICF (20-40)-6-5 is recommended.

Using the ICF (20-40)-6-5 the valve provides you

with an advanced ICM motor control valve with a

solenoid in front. It is delivered with a sight glass

in the side port of the valve housing.

For fail safe operation this type of ICF is equipped

with a ICFE solenoid valve in front of the ICM

motor operated valve.

The ICF consist of the following modules:

The ICF 20-6-5 is available in versions A, B and C,

referring to the capacity of the electronic motor

valve. ICF (25-40)-6-5 is available in version A.

Ordering

* Four side ports include four blind plugs and one ½ in. connector. Side ports in P2/P7 and P5/P10.

Six side ports include six blind plugs. Side ports in P2/P7, P4/P9 and P5/P10.
