Reciprocating Compressors

Description

TIGHT compressors combine sturdiness and small dimensions in order to provide the maximum
performance in the compression of technical gases, for stationary or transport uses.

TIGHT produces single-stage, two-stage or dual-seal compressors depending on the product to
be treated. The maximum working pressure is 18 barg for single-stage and 20 barg for two-stage
compressors (35 barg by request with special seals).

THE PRINCIPAL CHARACTERISTICS OF COMPRESSORS TIGHT:

● Oil-free compressors
● Twin-cylinder, positive-displacement, reciprocating compressors
● Pump induced lubrication
● Treated pistons in light alloy
● Special system with self-lubricating seals
● Chromium plated piston rods made of hardened carbon steel
● Crossheads made of special aluminium alloy
● Connecting rods with sliding friction bearings
● Oil sump

ADVANTAGES OF THE COMPRESSORS TIGHT

● Connection to the pipe by flanges or welded connections to minimize the risk of leakage
● Lack of threaded pipe connections
● 4-way valve installed in the block with flanged connection
● Compact arrangement for easy installation and service
● Mechanical trap for the liquid with a stop valve located in non-pressurized closure (PED
certificate)
● Steel base with supports to reduce vibration
● 2-year warranty
● Tight compressors have all certifications required by European standards:
– ISO 9001
– PED 97/23/EC certification
– Certification II 2 G T3 ATEX 94/9/EC
– Directive 98/73/EC

TIGHT oil-free compressors can handle a full range of air and technical gases without oil
contamination.
