Industrial Ammonia Refrigeration Controls

Product Details:

Application

• While primarily designed for Ammonia, this control is also suitable for R-22 and other non-corrosive liquids that have a specific gravity of 0.5 or more.
• The controller is ideal for the control of the operating level of liquid in liquid refrigerant accumulators and separators. Although this is normally done with a solenoid valve, the controller can activate an alarm or a pump or similar device.

Construction
This device consists of two separate units, the float chamber and the electronic controller. The float chamber consists of a housing, float ball, float coil and coil enclosure. The float ball is located inside the housing and moves an attached magnetic stem up or down in an enclosing tube from the top and is protected by the coil enclosure. The construction permits all high voltage connections and wiring to be made at a remote or non-hazardous location.

The Liquid Level Controllers are available in 2 models.

Type LC 101 AI & 39FI

The Liquid Controller consists of a float chamber and an electronic controller. It can be used on all non corrosive liquids such as Ammonia, Toluene, Freon etc.

The electronic controller has a bar graph display module installed to continuously display the rising & falling of liquid level inside the float chamber. The level controller is used to control the liquid level in various refrigeration applications.

These level controllers can also be used as a protection against too high & too low liquid levels.

SPECIFICATIONS :

•  Refrigerant R717 (NH3), HFC, HCFC.

•  Differential Adjustable between 10 to 40 mm.

•  Max operating pressure for float housing 19 bar.

•  Enclosure for float housing IP 65

•  Amplifier /  controller is  available in  IP  65  wall mounting enclosure or DIN 1/4 for panel mounting enclosure.

•  Float Chamber and Amplifier are also available in flame proof enclosure.

Product Details:

Type SA5 solenoid valve is the direct acting type & type SA 17, SA 32, SA 42, SA 50 are higher capacity pilot operated solenoid valves for refrigeration & air conditioning applications. SPECIFICATIONS :

•             Refrigerants : R717 (NH3), R22, R134A etc.

•             Temperature of medium -40°C to + 80°C

•             Single coil (type KC -3) for all SA series valves.

TYPE MS SERIES

These high quality valves are compact, strong and reliable. Stainless steel pistons with Teflon seals are used to overcome the problem of valve sticking due to dirt or lack of oil. Pilot seats are polished stainless steel on Teflon discs and main valve seats align for tight closing. These valves can be used in liquid. suction, hot gas, discharge, pump lines etc., where a strong opening, tight closing valve is required.

FEATURES :

•  All Valves are spring closing.

•  All Valves have Teflon seat. One Solenoid Coil fits all Valves

We have introduced new series of Microcontroller based controllers. The new MPRCC is complete controller to operate compressors / chiller packages / condensing units. It can be used for Multi Cylinder compressor or with RACK system of multiple compressors. The inbuilt features  are

•  Four Analog inputs ( 4 to 20mA) for pressure transmitter

e.g. compressor suction, discharge, oil and intermediate

•  Four Digital inputs (potential free)

•  Six Relay Outputs for Compressor Capacity Control

•  Solenoid Valves and Compressor start stop

•  Interlock for compressor start command

•  Inbuilt time delay for Differential Oil trip

•  Adjustable time delay for capacity control solenoid valves

•  Adjustable Neutral Zone, Inter Stage Differential,

Calibration

•  Optional RS232 / RS485 port for communication

•  Optional available Software for PC monitoring

Compact Single Enclosure unit. can be fitted into the panel Operates directly on 230VAC, 50Hz Supply. No need of auxiliary supply units

Main valves, type SPM 1 and SPM 3
Main valve type SPM is specially developed to regulate pressure and temperature in refrigeration, freezing and air conditioning plants with fluorinated refrigerants and ammonia. SPM is a pilot operated main valve with screwed-in pilot valves or pilot valves mounted in an external pilot line. Main valves type SPM are used in refrigeration plant with dry evaporation, pump circulation, natural circulation. The regulator is available in two variants, SPM 1and SPM 3. SPM 1 is designed to accept one pilot valve either screwed-in or mounted in an external pilot line. SPM 3 will accept three screwed-in pilot valves or pilot valves mounted in an external pilot line. Thus several functions can be performed by the same valve.

Product Details:

SPML valves are servo-operated main valves with screwed-on pilot solenoid valves. SPML valves use an external pressure source for opening (which means that no differential pressure across the SPML valve is required in order to maintain open state). This makes the valve especially suitable for low-pressure suction lines.

The SPML valves can be used in all types of refrigeration systems:

• Direct expansion

• Pump recirculation

• Natural circulation

Within their specifed pressure and temperature ranges SPML

valves can be used for fuorinated refrigerants (R 22, R 134a,

R 404a, R 12, R 502, etc.) or ammonia(R 717)

SPML pilot-operated solenoid valves can be installed in:

•   Suction lines

•   Return lines (liquid/vapour)

•   Pressure-equalising lines

•   Bypass lines

SPMLX are 2-step servo-controlled main valves with screwed- on pilot solenoid valves. SPMLX valves use an external pressure source for opening (which means that no differential pressure across the SPMLX valve is required).
