Electric expansion valve Type ETS 5M

For liquid injection into evaporators

ETS 5M is a compact and lightweight stepper motor driven electric expansion valve with a high level of reliability, and it provides a precise solution for expansion and ow control in a wide range of refrigeration and air conditioning systems.

The portfolio is available with a wide capacity range and is designed for use with uorinated refrigerants.

ETS 5M can be applied for applications i.e VRF, IT cooling, Heatpump, Mini Chiller, Bus / Transport application in single/biow operation.

Valve operation is by means of a uni-polar motor, and as such it is compatible with a number of electronic controllers from Danfoss or third-party vendors. With an EKE1 series/EIM 336 superheat controlleres and AKS sensor, a superheat accuracy better than ± 0.5 K can be obtained.

Features

• Low ow noise and operation noise.

• Optimized valve ow characteristic.

• Accurate valve control, also at low opening degrees.

• Bi-ow, with full performance in both ow directions.

• Higher degree of freedom of installation orientation.

• Future-proof regarding refrigerants.

• Compatible with existing valve drivers.

• Largest nominal capacity, R410A : 20.6 kW, 5.8 TR.

EIM 336 Superheat controller

EKE 1 series superheat controllers (EKE 1B is shown)

EIM 336 is designed as a controller on a pcb, i.e. must be built into a suitable cabinet before use.

EKE superheat controllers are for DIN rail mounting, and comes in three versions with dierent combinations of inputs and output relays and dierent functionality.

Pressure transmitter (DST P110 shown)

EKF 1A/2A Stepper Valve Driver

EKE 2U Backup power module

DST P110 is a digital ratiometric pressure transmitter. Depending on controller type, other ratiometric pressure transmitters can be used as well (e.g. AKS 32R).

EKF series is an economical stepper valve driver that translates analog signal provided by master controller to valve driving sequence .

EKE 2U Backup power module ensures sucient power in case of power failures to the controller to ensure closure of the electronic valves.

Electric expansion valve, Type ETS 5M

Portfolio overview

ETS 5M is a system product whose function is controlled through a Danfoss electronic controller, or a third party vendor electronic controller that is compatible with the ETS 5M as to control functionality and connections.

Danfoss recommends the use of the EKE1 series / EIM 336 superheat controller together with ETS 5M. (See separate data sheet on EIM 336 for details). with EKE1 series / EIM 336 or similar Danfoss electronic controllers, a superheat accuracy better than 0.5 K can be obtained.

The electronic controller requires precise temperature input from a temperature sensor (refrigerant temperature) and precise pressure inputs (evaporator pressure) from a pressure transmitter.

Product specication

Design

The ETS 5M Electric expansion valves open and close to regulate refrigerant ow by means of a screw, whose rotating motion is transformed into linear motion. This occurs by the rotation of a magnetneedle valve assembly which moves when electrical signals are applied to the surrounding coil. Within the coil structure, there are dierent winding congurations, and the polarities are changed by the electrical signals applied.

By application of the appropriate combination of signals, in the form of pulses, the coil forces the rotor of the valve to move in a stepwise fashion. Application of multiple pulses will make the valve mechanism move through a series of steps in the chosen direction, in order to set the valve with the required opening degree.
