Emerson manual Versatile VMC 450XL is now even better, Spring Loaded Safety Heads

450XL Cross Section

Spring Loaded Safety Heads

Protect against liquid slugging by relieving internal cylinder pressure if cylinders are subjected to an incompressible fluid.

Suction and Discharge Porting

Maximum suction and discharge porting through the compressor achieves minimum pressure drop with valve plates that are made to exacting Vilter material and manufacturing requirements for long-term service.

Piston and Connecting Rod

The unique design of the piston and connecting rod assembly allows for movement only between the con- necting rod bushing and piston pin, while providing positive lubrication throughout the entire compres- sion cycle.

Double Tapered Roller Bearings Energy-efficient roller bearings enable the compressor to be used for high suction pressure applications as well as high belt-drive horsepower requirements.

Tri-Micro® Oil Filter

Removes 95% of contaminants as small as 3 microns in size. Allows full flow of oil at all times, resulting in reduced wear on compressor components. Combines extreme filtering capacity with the convenience of a throw-away recharge element. Filter is enclosed in a seamless drawn carbon steel shell with cast iron cover, and is equipped with a means for determining pres- sure drop across the filter.

The versatile VMC 450XL is now even better!

While retaining all of the features that are exclusive to Vilter com- pressors, we’ve made several design improvements:

•Piston

•Connecting road and bearing insert

•Crankshaft

•Safety head

•Capacity reduction system

Even though we’ve made these specific changes, we’ve retained all of the exclusive Vilter features, including provisions for fast and easy servicing with components that are easy to access.

The 450XL can operate with ammonia, halocarbon and even some hydrocarbon refrigerants. It works in extreme applications with up to a 17,2 bar pressure differential. It can be belt-driven up to 224 kW or direct driven all the way up to 285 kW. And it can run at high compression ratios all the way up to 12:1 with certain halocarbon refrigerants.
