A compact water-cooled two-stage dry screw compressor package that combines a common-gear compression module, touchscreen controls and clearly separated plant utility connections.
- Compact 22 kW-class package
- Two dry screw compression stages
- Water-cooled common-gear module
مقدمة المنتج
The Oil-Free Screw Compressor is a compact enclosed package for clean process-air plants that need continuous rotary compression without lubricating oil entering the compression chambers. One electric motor drives a common gear module connected to a larger low-pressure screw stage and a smaller high-pressure screw stage. Water-cooled intercooling removes heat before the second stage, while an aftercooler and moisture separator condition the discharge before it leaves the cabinet. The selected two-door blue enclosure provides direct access to the compression module, coolers, controller and grouped air, cooling-water and drain interfaces. A receiver, dryer, final filters and point-of-use quality monitoring remain separate system selections rather than hidden inside this compact compressor package.
الخصائص الرئيسية
One motor and common gear module create a compact mechanical layout distinct from multi-scroll packages
A water-cooled intercooler reduces the thermal load entering the high-pressure screw stage
The downstream aftercooler and moisture separator remove bulk heat and condensate within the package boundary
Touchscreen control, green and amber status indication and a dedicated emergency stop support clear local operation
Two removable front doors place routine inspection points within one shallow service envelope
A powder-coated blue cabinet and graphite structural base protect the machine while retaining visible industrial color
Separate compressed-air, cooling-water and condensate connections simplify utility routing around the compact frame
مخاوف المنتج للعملاء
A small clean-utility compressor room still has to manage oil exposure, interstage temperature, service clearance and plant connections without turning one compact machine into an undefined complete air station.
A full-size compressor frame can consume the access aisle needed for other clean-utility equipmentUse the selected 1701 mm by 1016 mm compact plan and two front service doors to keep routine access concentrated along the front of the package.
Oil-injected compression creates an additional oil-removal burden for product-contact or instrument airUse two dry screw stages with isolated gear and bearing lubrication so lubricating oil is not introduced into either compression chamber.
Excessive first-stage discharge temperature can increase the load on the high-pressure stageRoute cooling water through the dedicated intercooler between stages and supervise stage temperatures from the package controller.
A compact enclosure can become difficult to troubleshoot when controls, utilities and service components are poorly organizedGroup the HMI, status lamps and emergency stop on the closed control door while placing the common-gear screw module behind the separate left service door and the plant connections on the rear-right face.
Oil-free compression is sometimes mistaken for a complete particle, moisture and microbial air-quality specificationSelect the receiver, dryer, final filtration and monitoring train separately for the required point-of-use pressure dew point and ISO 8573-1 purity classes.
