RadCon

Pressure Independent Radiator Valve

Frese RadCon is a pressure independent Radiator Valve (PIRV) for use in 2-pipe radiator systems.

Combined with the thermostatic sensor head, RadCon supports occupant comfort, efficient operation and simplified commissioning.

The valve can be preset from 20 l/h to 340 l/h (0.006 l/s to 0.094 l/s) and provides modulating control regardless of any fluctuations in the differential pressure of the radiator system.

It combines an externally adjustable presetting, a differential pressure controller and a modulating radiator valve.

Precise control of the water flow can be achieved, supporting occupant comfort and energy-efficient operation. Improved Δ

Benefits

Design

• Less time to define and select the right presetting. Just set the required flow for the radiator. No KV calculation needed
• Flexibility if the system is modified after the initial installation

Installation

• No further regulating valves required in the radiator system when the differential pressure does not exceed70 kPa
• Minimized commissioning time due to automatic balancing of the system
• Simplified radiator system design
• Thermostatic sensor with M30x1.5 connection

Operation

• High comfort for end-users due to high precision temperature control
• Anti-frost thermosatic head protects the system and reduces the risk of mould
• Reduced flow noise due to the built-in differential pressure controller in the valve.
• Helps prevent overflow through the radiator and supports efficient ΔT performance in the radiator system.
• Easy maintenance - replacable internals

Features

• The constant differential pressure across the modulating control component is designed to maintain full valve authority.
• Automatic balancing is designed to prevent overflows under varying pressure conditions in the system.
• Thermostatic sensor head with small dimension
• Differential pressure operating range up to 70 kPa
• Complete programme DN10-DN20
• Theft protection of thermostatic head
