Commercial Chiller Service, Retrofits and Booster Chilling Systems
Commercial chiller repair and industrial booster chilling systems for air- and water-cooled plants across Chicagoland, Northern Illinois & Indiana.
What this covers
Scope
- We diagnose, repair, and overhaul air-cooled and water-cooled chillers serving commercial buildings and industrial plants.
- We design, build, and install industrial booster chilling systems that add localized cooling capacity to existing chilled-water loops.
- We execute chiller retrofits and equipment changeouts, coordinating piping, rigging, electrical tie-ins, and controls integration.
- We fabricate custom chillers and skid-mounted booster assemblies in our in-house shop for non-standard footprint or process requirements.
Problems we solve
- Process temperature drift disrupts production lines when central chilled water cannot hold tight supply setpoints under peak summer loads.
- Compressor failures, fouled condenser or evaporator bundles, and refrigerant leaks trigger unplanned chiller shutdowns across the facility.
- Aging chillers with recurring refrigerant circuit leaks become costly to keep online.
- Plant expansions outgrow central cooling capacity where tearing out the main chiller room would halt ongoing operations.
Service modes
How we work it
24/7 emergency
Technicians respond around the clock across Chicagoland, Northern Illinois & Indiana to troubleshoot tripped chillers, isolate leaks, and restore cooling to critical facilities.
Planned work
Project crews stage chiller retrofits and booster chilling installations around tenant occupancy or plant shutdown windows to keep downtime predictable.
Maintenance
Preventive maintenance contracts cover seasonal chiller startup, heat-transfer surface cleaning, refrigerant circuit checks, and operating log review before peak cooling weather.
In the shop
Our in-house fabrication shop builds custom chillers and welded booster chilling packages tailored to tight mechanical rooms and specialized industrial processes.
FAQ
Questions facility managers ask
When does an industrial facility need a booster chilling system instead of a full chiller replacement?
A booster chilling system makes sense when the main plant runs fine on existing chilled water, but a specific production line or process load demands colder supply temperatures or extra localized capacity. Adding an in-house fabricated booster loop avoids tearing out a serviceable central chiller while stabilizing process temperatures where needed.
Do you service both air-cooled and water-cooled chillers?
Yes, our technicians repair, retrofit, and maintain both air-cooled and water-cooled commercial and industrial chillers across Chicagoland, Northern Illinois & Indiana. Work covers mechanical components, refrigerant circuits, heat exchangers, and building automation tie-ins.
Can you build a custom chiller if standard catalog equipment will not fit our mechanical room?
Yes, Pro Tech Contractors fabricates custom chillers and booster chilling systems in our own shop. Building the package in our shop lets us match existing piping connections, structural clearances, and industrial process requirements.
How do you handle chiller retrofits when older refrigerants are being phased out?
We evaluate whether the existing chiller warrants a retrofit or a full equipment replacement based on vessel condition, load profile, and operating reliability. We then schedule rigging, piping modifications, controls integration, and commissioning around your facility calendar.
