QANSAT ENERGY services and overhauls Howden Turbo screw compressors at industrial facilities across Kazakhstan: scheduled maintenance, major overhauls, rotor inspection and supply of genuine spare parts sourced directly from the manufacturer.
Experience with Howden equipment
Our serviced equipment list includes the Howden Turbo screw compressor model WRViTS580 193 48.
On screw machines the decisive factor is the clearance between the rotors and between the rotors and the casing. Once it opens up, capacity falls gradually and the loss is easy to write off as a process issue rather than compressor wear. That is why we base the decision to overhaul on measured clearances and vibration trend data, not on running hours alone.
Besides Howden we service equipment from the following manufacturers:
- Ariel Corporation — reciprocating gas compressors
- FS-Elliott Machinery — Polaris centrifugal compressors
- Shenyang Blower Works Group — centrifugal and reciprocating machines
- Shenyang Yuanda and Kobelco Wuxi — reciprocating and hydrogen compressors
- Xi'An Shaangu Power — axial compressors
- GEA Refrigeration, FIMA Maschinenbau

Frequently asked questions
Which Howden models do you service?
Our list includes the WRViTS580 193 48 screw compressor. For other models of this manufacturer, please check with us.
How do we know the compressor needs an overhaul?
The grounds are running hours against the OEM schedule, deviation in vibration readings, a drop in capacity and oil analysis results. We carry out diagnostics and issue a written assessment.
Can repairs be carried out on site?
In most cases yes. If the rotors require workshop restoration or balancing on a dedicated stand, we arrange logistics in both directions.
Do you supply genuine spare parts?
Yes, sourced directly from manufacturers through our own company Shanghai QANSAT Trading Co., Ltd., with certificates of origin and full traceability.
What warranty do you provide?
365 days on completed work. Genuine spare parts are supplied with full technical documentation.
