Refrigeration Chiller Installation
Our recent projects showcase our expertise in servicing and upgrading large-scale refrigeration and HVAC systems. Below are key highlights of the work we've completed:
- Dunham Bush Screw Compressor Overhaul: We recently overhauled a 1000-ton refrigeration chiller equipped with a Dunham Bush screw compressor. The unit, powered by a 1500hp motor with a 6600V supply, is currently awaiting a control system upgrade.
- Carrier Centrifugal Chiller Control System: We are in the process of designing and installing a complete new control system for a Carrier centrifugal chiller, a task we routinely handle for similar equipment.
- Shell and Tube Evaporator Refurbishment: Our team re-tubed a shell and tube evaporator with new baffle plates and insulation, which is now ready for site installation.
- Glycol Water Cooled Chillers: We supplied and installed two new glycol water-cooled chillers, ensuring efficient cooling performance for our clients.
- Trane Screw Package Chillers Overhaul: At Steve Biko Hospital in Pretoria, we overhauled Trane screw package chillers, restoring them to full operational efficiency.
- Hanbell Screw Compressor Overhaul: Utilizing our in-house armature winding facility, we mechanically and electrically overhauled a Hanbell screw compressor, delivering high-quality results.
- Ammonia Plant Speed Drive Installation: We supplied and installed a speed drive and control system for an ammonia plant in Gauteng, enhancing system efficiency and performance.
- Freon to Ammonia Compressor Modification: We successfully modified a Freon Carrier reciprocating compressor to operate on ammonia, a complex upgrade that required our expertise in retrofitting systems for optimized performance.
- Clivet Chiller Screw Compressor Overhaul: Following a significant mechanical failure, we overhauled the Fu Sheng screw compressor on a Clivet chiller, replacing a broken rotor shaft and adding additional safety measures to prevent future issues.
