KRK-A-TP • Circular bi-flow dampers with actuator

Round bi-flow control valves with actuator, opened when under current and with spring return

Minimal and maximal air volumes can be adjusted on site

• For air regulation in ventilation and airconditioning systems, cookerhoods, ...
• No Limited time under current
• Max. Temperature 60°C
• Maximum pressure 200 Pa
• Response time 8 seconds
• Consumption 2.5W

• Valve, housing and constant volume dampers made of fire retardant plastics
• Connections at both sides of the valve made of galvanized steel
• Actuator 230V with spring-return (only to be installed on the top side)

• Round body and motorized blade, each equipped with an adjustable constant volume damper in order to make the bi-flow control possible. The constant volume damper in the blade provides the minimum air flow rate when the blade is closed. The bigger constant volume damper in the duct provides the maximum air flow rate in the damper when closed.
• KRK-A-TP 125: adjustable from 15 to 50 m³/h (in the blade) and from 50 to 180 m³/h (in the duct)
• KRK-A-TP 150: adjustable from 15 to 100 m³/h (in the blade) and from 100 to 300 m³/h (in the duct)
• KRK-A-TP 160: adjustable from 15 to 100 m³/h (in the blade) and from 100 to 300 m³/h (in the duct)
• KRK-A-TP 200: adjustable from 15 to 100 m³/h (in the blade) and from 100 to 500 m³/h (in the duct)
• The desired minimum and maximum flow rate must always be specified with the order
• Actuator equipped with two supply cables and spring return
• Connection flanges for ducts

• To be mounted in between two round ducts
• Airstream direction mentioned on the valve to be taken into acount!
• Connected to current 230V by 2 wires 0,75 mm²

• The air regulation bi-flow valves shall be of the round type in fire retardant plastics, equiped with actuator with spring return. The valve will open at a current of 230V and wil automatically close when there's no more current. The valve will have two round duct connections in galvanized steel.
• Cairox Type KRK-A-TP

KRK-A-TP 160, 25 m³/h / 210 m³/h

Explanation

KRK-A-TP = Type of regulating damper

160 = Duct size

25 m³/h = Minimal airflow when valve is closed

210 m³/h = Maximal airflow when valve is open

• The desired minimum and maximum flow rate must always be specified with the order
