Frese ALPHA DN15-DN50

The Frese ALPHA Valves are particularly designed and manufactured for the automatic balancing of heating and cooling circuits. The Frese ALPHA Cartridges - the second generation cartridges - are an integral part of the Frese ALPHA Valves limiting the flow at the specified level even under fluctuating pressure conditions. The patented design of these cartridges introduces a replaceable orifice plate for higher flexibility and a resistant diaphragm for higher accuracy. From small size threaded valves (DN15) to big flanged type valves (DN800), from small heating units to district cooling applications, Frese ALPHA Valves guarantee the hydraulic balance of the system regardless pressure fluctuations.

Frese ALPHA DN50-800

The ALPHA valve is particularly designed and manufactured for the automatic balancing of both cooling and heating circuits. With the ALPHA cartridge as an integral part of the valve, the flow is limited at the specified even under fluctuating pressure conditions. This Frese ALPHA wafer-type valve can contain, depending on the size and the design flow, up to 85 Frese ALPHA cartridges.

Frese SIGMA Compact DN15-DN50

The Frese SIGMA Compact is an externally adjustable dynamic balancing valve that provides simple, accurate and reliable flow limitation and isolation in heating and cooling systems. The Frese SIGMA Compact can be used in both heating and cooling systems for the effective distribution of flow in various sections of the system. The Frese SIGMA Compact can be used instead of traditional double regulating valves and can be installed in both variable flow systems and constant flow systems. The Frese SIGMA Compact can be set to the required position easily by using the hand wheel to limit the flow rate in certain parts of a system, eradicating overflows and the unnecessary wastage of energy. The internal differential pressure control function of the Frese SIGMA Compact ensures that the set flow rate is limited irrespective of fluctuations in the differential pressure of the system. Once the valve has been set to the desired flow rate, the hand wheel can be locked in position. From this locked position, the valve can be fully closed for isolation purposes and easily re-opened back to the required set point.

Frese SIGMA Compact DN50-DN300

The Frese SIGMA Compact is an externally adjustable dynamic balancing valve that provides simple, accurate and reliable flow limitation and isolation in heating and cooling systems. The Frese SIGMA Compact can be used in both heatingand cooling systems for the effective distribution of flow in various sections of the system.The Frese SIGMA Compact can be used instead of traditional double regulating valves and can be installed in both variable flow systems and constant flow systems. The Frese SIGMA Compact can be set to the required position easily by using the scale, to limit the flow rate in certain parts of a system, eliminating overflows and the unnecessary wastage of energy. The internal differential pressure control function of the Frese SIGMA Compact ensures that the set flow rate is limited irrespective of differential pressure fluctuations in the system. The hand wheel can be used to close the valve and to open it to the preset flow.

Frese ALPHA Cartridges

The Frese ALPHA Cartridges are particularly designed and manufactured for the automatic balancing of heating and cooling circuits. They are integral part of the Frese Dynamic Balancing Valves keeping the flow constant at the specified level even under fluctuating pressure conditions. From small size valves (DN15) to big wafer types (DN800), from small heating units to sea-water district cooling applications, there is a Frese ALPHA Cartridge that can guarantee the specified flow. The advanced patented design of the Frese ALPHA Cartridges introduces the orifice plate concept for higher performance and flexibility. With the Frese ALPHA Cartridges it is no longer needed to change the cartridge every time the design flow is modified. Each cartridge contains an orifice plate specific for every flow that can be easily removed and replaced by another one.
