The FCS Modular Mechanical Room, a complete heating or cooling solution that’s fully enclosed and can be configured to suit your most complex needs.

Whether it’s a modular chiller plant or other custom HVAC or cooling system, our engineers will work with you to provide an industrial solution that’s smart, efficient, robust and engineered to last while saving operating and maintenance costs. Our modular mechanical rooms are designed to make the installation and start-up process as easy as possible. Simply run power to our control panel and connect your inlet and outlet pipes and you’re ready to go. Every system goes through an in-shop run-off procedure to guarantee a successful start-up of each modular system in the field. As with all of our products and solutions, each system is covered by a limited two-year warranty. We also offer maintenance and service plans so you can enjoy worry-free operation beyond our warranty period.


There are many high level business business benefits as well as long-term operational benefits obtained by close-coupled, piped and wired compact enclosed outdoor mechanical rooms. Fluid Cooling Systems has expertise working with many components in modularized and often enclosed spaces including electric and absorption chillers, variable and fixed speed pumps, boilers, heat recovery systems, cooling towers and dry-coolers and more.

Factory built mechanical rooms are consistently less costly than field built approaches. By as much as 25%.

Fluid Cooling Systems enjoys the fact that our equipment saves thousands of kilowatts and the carbon to produce it.

By integrating FCS controls with oil-free chillers, there is less fouling in the heat evaporator and condenser so the chilled water system energy input becomes sustainable.

Further, new technologies allow us to provide chilled water systems with highly stable states that permit us to integrate direct refrigerant injection and thereby dynamically reset the pressure-ratio of our oil-free chillers to enable precise matching of actual demand-to-work (lift) in the compressors. Future developments may include direct DC/DC bus to use fuel-cell power at high-efficiency.

Integrating the engineering, assembly, fabrication, piping, wiring, testing and commissioning of complex systems with Fluid Cooling Systems assures long-term performance and highest ROI. We can provide ongoing support and maintenance upon request.

Shifting the mechanical room work offsite to a remote factory reduces site construction risks due to missed coordination across disciplines, labor availability, equipment room worker safety, and COVID related protocols and initiatives. In fact, secure FCS mechanical rooms can be equipped with features such as worker temperature monitoring for access.

The approach provides higher short and long-term value and mitigates risks.

By choosing a modularized approach, critical complex equipment and their inter-connects are done in parallel and more rapidly. site workers can prepare for the modules and mechanical rooms to arrive. This approach compresses the time value of money invested by owners.

Field built, complex mechanical systems must be properly interconnected across spaces while preserving pressure loss and temperature changes that affects downstream equipment ideal operation.

Performance, and more importantly, the energy it requires to overcome site-related realities is unfortunately inherent in traditional equipment rooms, but avoided in engineered compact modular spaces. Further, by moving the mechanical room outdoors, more valuable facility space is made available.

Modularization may be the optimum path to reducing facility carbon footprint with the responsible use of physical resources, space, money, people and energy for mechanical equipment.
