Hand Expansion Valves (52bar)

These precision-calibrated, adjustable, slotted plug flow regulating valves (hand expansion valves) are ideal for metering or flashing expansion of liquid refrigerants. Their slotted plugs are more tolerant of dirt particles an are common metal-seated tapered-plug expansion valves, and are less susceptible to wire drawing.

All valves have near linear flow characteristics per turn open and are tight closing with Teflon seats. These valves have stainless steel stems with back seating or seal replacement. The patented non-leak seal plus packing design permits low torque operation for valve adjustments since the packing nut requires little tightening. Suitable for ammonia, CO2, or halocarbons.

ST Strainers (52bar)

These rugged Strainers (Filters) are specifically designed to facilitate the removal of foreign materials from refrigeration systems. Strainers help prevent damage to valves and other components, thereby reducing costly service and downtime. They can also be installed as a separate unit. They are available in 1/2″ to 6″ (13 mm to 150 mm) sizes.

Butt Weld Shut-Off Valves (52bar)

These low pressure drop refrigerant shut-off valves are designed to be butt-welded directly to steel piping, thereby eliminating potential leaky flanges or threaded joints and simplifying installation.

Forged and cast steel bodies are lightweight, yet have substantial wall thickness to help overcome corrosion loss. The cast steel body is rigid, reducing the potential for seat leakage due to flexing of the valve body under abnormal conditions.

CHCK5DW Gas Powered 2-Step Suction Stop Valve

These heavy-duty, gas-powered, 2-step suction stop valves are designed to control the flow of refrigerant in large industrial and commercial refrigeration systems.

They remain normally open via a spring and require no pressure drop to operate. A single pilot solenoid valve is required to control a higher pressure refrigerant gas which closes these valves during defrosting.

The CHCK5DW valve has an internal, controlled bleed-down (equalize) feature which will not allow the main seat to open until the pressure across the valve is at a lower, safer pressure differential.

CHS8W Solenoid Valve

This heavy-duty CHS8W refrigeration solenoid valve is compact and pilot-operated. It now features a higher pressure rating and maximum opening pressure differential (MOPD) suitable for CO2 and other approved refrigerants.

CARW Modulator Pressure Regulators

These advanced-design, strong-bodied, precision manufactured MODULAR regulators are superior in their ability to overcome dirt and sticky oil during opening and tight closing. Models are now available for nearly every control function requirement of subcritical CO2 refrigeration systems, industrial ammonia and commercial halocarbon refrigeration.

These regulators are ideal for cold storage plants, poultry plants, meat packing, fish processing, freezers, ice plants, breweries, bottling plants, heat recovery units, petrochemical plants, pharmaceutical plants, supermarkets, and many others. Applicable for CO2, FREON as well.

POP-EYE™ Insight

Introducing the revolutionary POP-EYE Insight with Remote Indication by Hansen Technologies – a game-changer in the world of refrigeration system management.

This innovative product not only establishes the “Time and Duration” of a release or event but also provides immediate awareness by facilitating prompt estimation of refrigerant release amounts. It helps you determine if and when a Release Notification is needed, thereby ensuring maximum safety and compliance.

POP-EYE™

Designed to provide emergency relief from excessive pressure
in refrigerant-containing vessels, these valves are built in
strict conformance with ASME Boiler and Pressure Vessel
Code requirements for safety relief devices. Each valve
bears the ASME code symbol of certification (UV). Their
capacities are rated by the National Board of Boiler and
Pressure Vessel Inspectors. These tamper-resistant valves
are accurately set and sealed by qualified technicians at
the factory. POP-EYE lift detection is standard on all H56xx
series valves and includes an on board, 360° bright LED to
indicate when a relief valve has lifted.

APM | APMF Auto-Purger

A compact version of the original AP Auto-Purger, the APM Auto-Purger is ideal for medium size systems, up to 200 tons (703kW). Like the AP, the APM features automatic start-up with electronic control.

Designed for up to four purge points, an electronic “brain” searches for non-condensible gases in the system and purges at those points where air is present.

The APM includes an automatic water bubbler and comes standard with a NEMA 12, 13 control cabinet.

For use with ammonia or halocarbon refrigeration systems. CE and CSA certified.
