Trebles

The Trebles - RAC Pump package assemblies, are a pre-engineered solution designed for use in sealed cooling systems in combination with air handling units. This item includes a circulation Pump, pressure Vessel, low pressure Switch, safety valve and other associated ancillaries all housed within a Galvanised Steel frame, a Trebles - RAC unit can greatly reduce time spent on site during installation.

The pump is regulated by a 0–10V control signal from the air handling unit, ensuring precise synchronisation. It incorporates built-in dry run protection along with an automatic air purge function. The RAC pump package is supplied with a control box, pre-wired for 0–10V signal input, remote start/stop capability, pump alarm output, and a low-pressure switch. Once commissioned, the RAC unit is designed to operate unattended for extended periods, requiring minimal maintenance.

When plant room space is at a premium, the enclosed option facilitates external installation, protecting
the equipment with a Marine Grade Aluminium enclosure that is easily removable for future service &
maintenance.

The Trebles - ECO-BOOST combines energy efficiency with reliable performance while reducing overall space requirements. Backed by over 60 years of manufacturing expertise, this unit provides a straightforward, high-quality solution for water boosting applications.

Following installation, the system pressure is constantly monitored via a pressure transducer. Upon detecting a pressure drop caused by an open outlet, the unit automatically activates to maintain the set point. Variable speed drives will only run the Pump at the speed required thus saving huge amounts of energy compared to traditional methods of Pump control.

The ECO-BOOST range uses the latest horizontal multi-stage Stainless Steel Pumps equipped with IE3 motors in accordance with EN standards to ensure comfort, reliabilty and efficiency.

Our wide Pump range and numerous options and accessories help us to tailor an ECO-BOOST unit to your specific requirements.

Product Features:

• Dry Run Protection
• Variable Speed
• Anti-Vibration Mounts
• Auto-Changeover
• Constant Pressure
• Flow Through Vessels
• Overload Protection
• Duty/Standby with Assist
• Volt Free Contacts for BMS

Trebles - Eco-Boost Range is now KUKreg4 Certified
