Frese ALPHA Cartridges

Dynamic regulation in cooling and heating units

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 (DN1000), from small heating units to sea-water district cooling applications, there is a Frese ALPHA Cartridge designed to maintain 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.

Application

Frese ALPHA Cartridges is used in heating and cooling systems for the distribution of flow in various sections of the system.

The dynamic balancing valve is designed to provide reliable balancing of the system under varying differential pressure conditions. Frese ALPHA Cartridges limit maximum flow in the system and support efficient system operation. Can be used in both variable and constant flow systems.

From small size valves (DN15) to big wafer types (DN800), from small heating units to district cooling applications, there is a Frese ALPHA Cartridge designed to maintain the specified flow.

Benefits

• Quick and easy selection as only flow data are required. 
• Helps ensure that the specified flow is not exceeded.
• Easy to install according to pre-defined flow. 
• Minimized commissioning time due to automatic balancing of the system.
• Supports occupant comfort through correct hydraulic balancing.
• The valves automatically adjust to pressure variations to maintain hydraulic balance.
• No main circuit or branch balancing valves needed in the system. 
• Improved response to water hammer due to the chock absorption by the rubber diaphragm of the cartridge.

Features

• Removable cartridge solution simplifies flushing procedure 
• No minimum straight pipe lengths required before or after the valve.
• Built-in optional P/T plugs for needle system. 
• Minimized friction and noise due to the patented cartridge design based on the metal-rubber diaphragm-metal contact.
