System Protectors

Alco Controls range of filter driers includes both hermetic and take-apart filter driers, with versions for all fluorinated refrigerants, with 100% molecular sieves or composite cores. Hermetic filter driers are available as standard, bi-flow, combination (with receiver) and burn-out. The program for driers with replaceable cores includes shells for 48 to 192 cubic inches standard core for CFC and HCFC refrigerants, and standard core, burn-out core, and mechanical filter. Alco's sight glasses are used to monitor flow, level, condition, and moisture content of system refrigerant. Versions for CFC, HCFC, and HFC refrigerants are offered. Models are offered for line, crankcase, and receiver monitoring. The market's premium compressor and refrigeration system protector.

EX Series Electrical Control Valves

EX4 / EX5 / EX6 / EX7 / EX8 are stepper motor driven valves for precise control of refrigerant mass flow in air conditioning, refrigeration, heat pumps, close control, and industrial process cooling applications.

The Control Valves can be used as thermo-expansion duty, liquid injection duty, hot gas bypass, evaporator pressure regulator, crankcase pressure regulator, head pressure
regulator, or liquid level control. This data sheet describes only the performance of the valves.

Features
• Multifunction as expansion valves, hot gas bypass, suction gas throttling, head pressure, liquid level actuator etc.
• Fully hermetic design (no thread joints between valve body and motor compartment)
• Applicable to all common refrigerants (HCFC, HFC) and for subcritical CO2 applications
• Stepper motor driven
• Short opening and closing time
• Very fast full stroke time
• High resolution and excellent repeatability
• Bi-flow versions for heat pump applications
• Positive shut-off function to eliminate the use of an additional solenoid valve
• Linear flow capacity
• Extremely wide capacity range (10 … 100%)
• Continuous modulation of mass flow, no stress (liquid hammering) in the refrigeration circuit
• Direct coupling of motor and valve for high reliability (no gear mechanism)
• Ceramic slide and port for accurate flow and minimal wear
• Balanced force design
• Corrosion resistant stainless steel body and stainless steel connections

An awful effect of a fake filter drier.

The supermarket refrigeration system suffered because fake filter driers were used. Several call backs, money and time wasted as a result.
