THERM-CONNECT

WITH INTEGRATED FROST PROTECTION

• Highly efficient, multi-step high-pressure centrifugal pump with inline connections. All pumps are equipped with a user-friendly mechanical seal in cartridge construction and a seal suitable for glycol for easy maintenance. At least IE3-standard motors (≥ 0,75 kW) with motor protection as cold conductor.
• Frequency converter for stepless speed control of high-pressure centrifugal pumps. The converter is a com-plete unit with programming and operating unit with clear text unit and integrated repair switch.
• Up to DN50: three-way valve with external thread, PN16, housing made of red brass, electromotive actuator.
• Membrane expansion tank with 10 bar maximal pressure and cap valve, approved up to 50 % frost protection.
• Up to DN50: strainer with sleeve connection in slanted design, PN16, exchangeable sieves by slanted design, installed in front of the high-pressure centrifugal pump for optimal protection of pump components.
• Regulation integrated in frequency converter for easy control by 0-10V signal and release of GLT, integrated adjustment of frost protection by temperature sensor on water side and control of three-way valve.
• Up to DN50: ball valve made of corrosion-proof red brass, PN10, ball valves on exits of hydraulic module for shut-off during maintenance.
• Very compact construction for small place requirement in ventilation center
• Larger than DN50: on request, with modified housing dimensions.

THE HIGH-PERFORMANCE KVS

• Highly efficient, multi-step high-pressure centrifugal pump in vertical design with inline connections. All pumps are equipped with a user-friendly mechanical seal in cartridge construction and a seal suitable for glycol for easy maintenance. At least IE3-standard motors (≥ 0,75 kW) with motor protection as cold conductor.
• Frequency converter for stepless speed control of high-pressure centrifugal pumps. The converter is a com-plete unit with programming and operating unit with clear text unit and integrated repair switch.
• Up to DN50: three-way valve with external thread, PN16, housing made of red brass, electromotive actuator; from DN50 upwards: three-way valve with flange connection, PN16, valve housing in ductile cast, electro-motive actua-tor.
• Energy-optimal control system by freely programmable DDC-controller, adjustment of programming to the in-dividual requirements of the project, control via BACNet possible, permanent communication of operating conditions with GLT.
• Membrane expansion tank with 10 bar maximal pressure and cap valve, approved up to 50 % frost protection.
• Up to DN50: ball valve made of corrosion-proof red brass, PN10; from DN50 upwards: maintenance-free soft-seal intermediate flange shut-off flap with centering lugs, PN16, ball valves before the pump for shut-off during maintenance, additional ball valves on the exits of hydraulic module.
• Switchboard made of powder-coated sheet steel, DDC-controller installed in switchboard, 8-line display in switchboard door, inside lighting and socket 230V in switchboard, cable entry internal from below, external from above, door hinge right- or left-hand.
• By a constant supervision of the air inlet and outlet quantities by pressure sensors on the fan jet as well as temperatures before and after the registers, the heat recovery rate can be determined and the system always be operated in optimum efficiency.
• Up to DN50: strainer with sleeve connection in slanted design, PN16, exchangeable sieves by slanted design; from DN50 upwards: welded flange strainer, installed before the high-pressure centrifugal pump for optimal protection of pump components.
