Rental Chiller Solutions

Taking the central cooling system offline for maintenance, overhaul or replacement can create a temporary capacity need for production. The load on the lines that will keep running during this period is determined, and the required cooling capacity and connection layout are planned accordingly.

At Carnot, we handle installing the rental system and taking the existing equipment offline within the same working schedule. By assessing pipework, electrical supply, valve layout and the changeover steps in advance, we aim to keep production supported throughout the maintenance period.

The capacity lost to an unexpected breakdown can raise process temperatures and constrain production. When defining a temporary cooling solution, the production lines that need protecting and the minimum capacity required come first.

Equipment, transport and site connections are organised based on unit suitability and availability. The temporary system's electrical and hydraulic requirements are checked and the commissioning process planned accordingly.

Rising outdoor temperatures in summer, combined with higher production volumes, can push existing cooling infrastructure to its limits. Additional rental capacity helps meet the cooling production needs during these busy periods.

We assess the capacity a rental unit can actually deliver at the real water and outdoor temperatures involved. Options for connecting in parallel with the existing system, or feeding a specific production line independently, are examined in terms of flow distribution, pump operating conditions and temperature control.

Permanent cooling infrastructure may not yet be ready while new machines are being trialled or during pilot production and capacity testing. Using a temporary chiller creates the temperature and flow conditions these trials need.

Test duration, variable loads and the equipment's technical requirements are assessed together. The operating data gathered during this period can also help define what the permanent cooling system will need.

Required cooling capacity is determined from process load, target supply and return temperatures, fluid properties and length of use. Equipment selection weighs nominal capacity alongside its actual performance under real operating conditions.

For applications needing low temperatures or a glycol fluid, the unit's operating limits, capacity derating and pump requirements are assessed separately.

For a rental unit to work properly with the plant, the required flow rate and pressure conditions need to be met. Pipe or hose length, connection sizes, and the pressure losses created by filters and heat exchangers are all factored into pump selection.

Where the unit connects into an existing system, we examine how the circuits interact, minimum flow requirements, and whether hydraulic separation through a heat exchanger is needed.

Electrical supply, connected load, protection devices and cabling requirements are assessed for the selected equipment. Unit placement takes airflow, avoiding hot-air recirculation, service access and handling conditions into account.

After installation, water circulation, sensors, operating settings and protection functions are checked. The unit's operation under the actual process load is assessed, and the operating team is briefed on use and alarm monitoring.

Over the rental period, maintenance, technical support and, at the end of use, removal are carried out according to the agreed service scope.

Assessing a critical facility's temporary cooling needs before a breakdown happens can reduce the preparation needed when responding to one. The processes that need protecting, the capacity required, unit placement and connection points are determined in advance.

The preparation work considers electrical supply, pipe routing and changeover sequence together. Comparing how long the process can tolerate a stoppage against the equipment's lead time and installation time determines what standby capacity needs to be ready on site.
