Defrost Controller
Frost Control is a complete electronic controller with Real Time for Hot Gas / Electrical / Water Defrost System from Manik Engineers

Features:
The Manik Frost Control Defrost Control System is designed to control the evaporator operations for large ammonia and halocarbon refrigeration systems. The Frost Control performs the functions of the following independent control systems:
- Evaporator Valve Group Status Monitor
- Multi-Function Defrost Clock
- Remote Communication
- Automatic Defrost Cycle with Real time clock

Evaporator Valve Group Status Monitor
The Frost Control has Alpha Numeric Display, which consistently indicates the cycle status and evaporator Valves status.

Humidity Transmitter
The FKH-140 and FKH-240 series of transmitters are specifically designed for use in applications where accurate measurement of RH at remote monitoring station is required. Each product includes an RH transmitter conveniently designed onto one PCB to ensure the highest accuracy and reliability available.

The FKH-140 is a voltage output (1 to 5 VDC) and FKH- 240 is a current out put (4 to 20mA) transmitters.

The FKH-140 and FKH-240 both models are available in Wall Mount as well as Duct Mount enclosures. The FKH-140 and FKH-240 comes standard in the Designer Space enclosure designed for ease of installation with IP65.

The FKH-140 and FKH-240 operates on 24 VDC and is available with either voltage or loop powered current output signals for RH.

Pressure & Temperature Regulators Type SPM & Pilot Valves
Main Valves, Type SPM 1 and SPM 3
Main valve types 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 types 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.

Non Return Valves Type SNRVA
Check valve type SNRVA can be used in liquid, suction and hot gas lines in refrigeration and air conditioning plant with ammonia. SNRVA can also be used in refrigerating systems with fluorinated refrigerants. When the SNRVA is used in liquid lines where cold, thick oil or impurities may be present, it is recommended that the standard spring be replaced by a special spring.

Features:
Ensures correct direction of flow, Prevents back-condensation from warm evaporator to cold evaporator. Fitted with damping piston that makes the valves suitable for installation in lines where pulsation can occur, e.g. in the discharge line from the compressor.

Thermostatic Expansion Valves
The Thermostatic Expansion Valve (TEV) controls the flow of liquid refrigerant entering the direct expansion (DX) evaporators maintaining a constant super heat of the refrigerant vapour at the outlet of the evaporator.

Type SVE2, 3, 4, 5, 8, 10 are external equalizer with solder connections. Type HVE 7, 11, 16, 20, MVE21, 34, 42 VVE52, 70, 100 are external equalizer with weldable flange connection.

Various ranges of the power assembly are available from +20 deg C to -40 deg C.
