Data Sheet

Motor operated valve, type ICMTS
with actuator, type ICAD 600A-TS

The ICMTS is a direct operated motorised valve
driven by actuator type ICAD 600A-TS. The
ICMTS is designed to regulate the ow of
transcritical gas or subcritical liquid from the
gascooler in transcritical CO2 systems. The

ICMTS can also be used for other control
functions in CO2 systems. The ICMTS valve is

designed so that the opening and closing
forces are balanced.

ICAD 600A-TS actuators can be controlled using
the following signals:

• 0 – 20 mA

• 4 – 20 mA (default)

• 0 – 10 V

• 2 – 10 V

ICAD 600A-TS actuators can also operate an
ICMTS valve as an On/O function supported
by a digital input.

The ICMTS valve can be operated manually via
the ICAD 600A-TS actuator or via the Multi­function tool for ICMTS (see the Ordering).

The actuator type 600A-TS is designed
specically for ICMTS valves. The actuator type
900 can be used for ICMTS as well, however it
consumes more energy than ICAD 600A-TS for
similar applications.

The ICAD 600A-TS is controlled via a
modulating analogue signal (e.g. 4 – 20 mA / 2
– 10 V) or a digital ON/OFF signal. ICAD 600A-TS
incorporates an advanced MMI (Man Machine
Interface), including continuous display of
Opening Degree, which gives the user a very
advanced and exible setup procedure that can
meet many dierent applications. The ICMTS
valve is typically controlled by the Danfoss EKC
326A controller.

Motor operated valve, type ICMTS with actuator, type ICAD 600A-TS

Function

ICMTS valve

The ICMTS motor valve is designed for use with ICAD 600A-TS.

The driving force from the actuator is transferred via a magnetic coupling (a) through the stainless steel top housing
(b), thus eliminating the need for a packing gland. The rotational movement of the magnetic coupling (a) is
transferred to a spindle (c) which in turn provides the vertical movement of the cone (d) and PTFE valve plate (e), to
open and close the valve. The closing force of the actuator combined with the PTFE valve plate (e) and valve seat (f)
provides an eective seal to prevent leakage across the valve port, when the valve is in the closed position. To
prevent damage to the PTFE valve plate (e) and seat (f) from system debris, it is recommended to install a lter in
the system.

Valve inlet pressure (P1) acting on the underside of the PTFE valve plate (e) also passes through the hollow cone
assembly (d) on to the top of the piston (g) and balances the pressure acting on the piston (g). Any trapped liquid
across the throttle cone (d) is equalised down to the valve outlet without aecting the valve performance.

Figure 1: ICMTS

The actuators have a fully weather protected enclosure with none of the moving parts exposed to the environment.

The fast acting actuators and balanced valve design results in the valve being able to move from the fully closed to
the fully open position in about 3 seconds.

The smallest cones (A33 and A) are log-shaped in order to provide optimum regulation at small capacities and high
pressure dierentials.

The rst version of the ICMTS valve features V-shaped A cones. Please contact your local Danfoss sales
company for further info.

Bigger cones (B and C) are V-shaped in order to provide an optimum regulating curve for higher capacities.

ICAD 600A-TS actuator

The design of ICAD 600A-TS is based on a digital stepper motor technology combined with an advanced MMI (Man
Machine Interface), that gives excellent possibilities for having a high degree of exibility with the same type of
ICAD 600A-TS actuator.

The Opening Degree (0-100 %) of the actual ICMTS valve installed can be continuously observed on the ICAD 600A­TS display.

The advanced menu system will allow several parameters to be adjusted to obtain the required function.

Many dierent parameters can be congurated, among these:

• Modulating and ON/OFF control

• Analogue input
0 – 20 mA or 4 – 20 mA
0 – 10 V or 2 – 10 V

• Analogue output
0 – 20 mA or 4 – 20 mA

• Automatic or manual control

• Change of ICMTS valve speed

• Automatic calibration

• Multiple Fail Safe set-up options during power cut

For service all Input and Output signals can be recalled and observed from the ICAD 600A-TS display.

A password protection has been linked to the parameter of entering the correct ICMTS valve to avoid unintentional
and non-authorised operation.

Application

ICMTS valve

Figure 2: Application

The ICMTS valve is developed for transcritical CO2 applications. The ICMTS valve can be used in systems with ash
gas bypass, parallel compression as well as in stand-alone application. The ICMTS valve can be used in transcritical
and subcritical conditions.

The most typical application is with ash gas bypass.

Pressure optimisation is performed by the Danfoss EKC 326A controller and the ICMTS valve which is installed at the
outlet of the gas cooler (see Figure 2: Application). This design provides the possibility to optimise gas cooler
pressure and intermediate receiver pressure independently.

The pressure in the receiver is one important parameter, but the design of the receiver is also important. It typically
acts as a liquid separator as well.

In order to keep the intermediate pressure low, ash gas is expelled through a gas bypass valve to the suction side
of the compressor. The two phase mixture from the ICMTS valve has to be separated before gas enters the gas
bypass.

Please refer to the Danfoss Application guide, DKRCE.PA.R1.A for more information on CO2 systems.

Media

Refrigerants

Applicable to R744 (CO2). ICMTS valves must not be used with ammable refrigerants. For further information,
please contact your local Danfoss sales company.

New refrigerants

Danfoss products are continually evaluated for use with new refrigerants depending on market requirements.

When a refrigerant is approved for use by Danfoss, it is added to the relevant portfolio, and the R number of the
refrigerant (e.g. R513A) will be added to the technical data of the code number. Therefore, products for specic
refrigerants are best checked at store.danfoss.com/en/, or by contacting your local Danfoss representative.

Buer time is dened as the period whereICAD 600A-TS is only powered from the ICAD-UPS (i.e. not from main supply). On ICAD-UPS there is an
adjustable buer time setting (1, 2, 3, 5, 10, 15, 20, 30 min. or innity). If set to 3, ICAD-UPS will switch o power to connected ICAD 600A-TS, 3
minutes after the power failure occurs. This ensures that the internal battery inside ICAD-UPS does not fully discharge.

ICMTS capacities

It is relatively complex to correctly size a valve for transcritical applications, especially as the mass ow of the
refrigerant changes, drastically moving from transcritical to subcritical conditions. At the same time, temperature
variations in the intermediate vessel downstream of the valve, will not signicantly aect the sizing the valve.

It is recommended to calculate the ICMTS valve using Danfoss DIRcalcTM software following these steps:

• Calculate the ICMTS valve as an expansion valve in the liquid line with the following conditions: Tcond = +30 °C,
Tevap = temperature in the intermediate vessel, 0 K subcooling.

• Check the selected valve for the winter conditions: e.g. Tcond = +15 °C with 5 K subcooling

• Possible part load of the system at Tcond = +30 °C, Tevap = temperature in the intermediate vessel, 10 K
subcooling. (night operation or the smallest capacity step of the power pack). The part load of the valve should be
above 10%.

Quick capacity selection could be done using the following table:

Table 6: 0 K subcooling in the subcritical mode

Table 7: 5 K subcooling in the subcritical mode

Table 8: 10 K subcooling in the subcritical mode

Please contact your local Danfoss sales oce if you need assistance in your selection of ICMTS valves.

Alarms

Table 11: Alarms

If an alarm has been detected, the ICAD 600A-TS display (see

Figure 12: Display) will alternate between showing

Actual alarm and Present Opening Degree.

If more than one alarm is active at the same time, the alarm with the highest priority will take preference. A1 has the
highest priority, A5 the lowest.

Any active alarm will activate the Common Digital Alarm Output (Normally Open).

All alarms will automatically reset themselves when they physically disappear.

Old alarms (alarms that have been active, but have physically disappeared again) can be found in parameter ¡11.
