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.
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.
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 MODULA is a compact and versatile valve system that combines the Frese range of dynamic flow, pressure and temperature control valves with isolation, flushing, draining and measurement components within a prefabricated, tested and ready to install terminal bypass unit.
Frese MODULA PRO is a compact and versatile valve system that combines the Frese range of dynamic flow, pressure and temperature control valves with isolation, flushing, draining and measurement components within a prefabricated, tested and ready to install terminal bypass unit.
Designed to combine automatic balancing and full modulating control regardless of the preset flow.
The innovative design of Frese OPTIMA Compact introduces an intelligent control valve that adjusts automatically to the preset flow in order to provide full modulating control. When the installer presets the valve according to the maximum designed flow, the stroke of the control valve remains the same thus providing 100% modulating control.
In practical terms, Frese OPTIMA Compact ensures that there is no overflow and that below the design flow the actuator has absolute authority. Furthermore, Frese OPTIMA Compact combines all those features that are necessary to ease the work of designers and installers:
• The wide (up to 800kPa) differential pressure range meets the requirements of most applications
• The compact design and the user-friendly presetting unit guarantee easy installation and commissioning.
Frese OPTIMA Compact pressure independent control valve (PICV) is used in heating and cooling systems with Fan Coil Units, Chilled Beams or other terminal unit applications. Frese OPTIMA Compact provides modulating control with full authority regardless of any fluctuations in the differential pressure of the system. It combines an externally adjustable automatic balancing valve, a differential pressure control valve and a full authority modulating control valve. 100% control of the water flow in the building is achieved easily, while creating high comfort and energy savings at the same time.
An additional benefit is that no balancing is required if further stages are added to the system, or if the dimentioned capacity is changed. Energy saving due to optimal control, lower flow and pump pressure. Maximized ΔT due to faster response and increased system stability.
