Proportional Fan Speed Control is  no longer included within ATC’s standard option and accessory offering.

Where an application requires variable fan speed control to suit specific operating or environmental conditions, ATC can review the cooling and control requirements to determine whether a suitable non-standard solution can be offered.

Availability will depend on the selected chiller, required functionality, and compatibility with the current system design.

Visit our Non-Standard Cooling Solutions page to find out how specialist requirements are assessed, or contact the ATC team to discuss your application.
