Danfoss KP Series Pressure Controllers for Refrigeration Systems

Danfoss Pressure Controllers and Switches

Product Introduction

Danfoss offers a range of pressure controllers and switches, including the KP Series (KP5, KP15, KP35, KP36) high-pressure switches and other models like RS750, RT200, RT116, RT112, BCP5, BCP3H, BCP6. The KP Series, in particular, is designed for refrigeration and air conditioning systems, providing protection against excessively low suction pressure or high discharge pressure. They also function to start and stop refrigeration compressors and fans on air-cooled condensers. Compatible with single-phase AC motors up to approximately 2 kW (and integrable into control circuits of DC motors and large AC motors), KP switches feature a single-pole double-throw (SPDT) design, with switch position determined by pressure settings and connector pressure. Available with IP30, IP44, or IP55 enclosures, these devices (along with other listed models) meet CE certification, are 100% brand new, and are manufactured in Poland, ensuring reliability for diverse industrial applications.

Features

Protection & Control Functions: KP Series switches safeguard refrigeration and air conditioning systems from extreme pressures (excessively low suction or high discharge) and manage the operation of compressors and condenser fans.

SPDT Switch Design: Equipped with a single-pole double-throw switch, enabling versatile control logic based on pressure conditions.

Ultra-Short Bounce Time: Snap-action function minimizes bounce time, reducing wear and enhancing long-term reliability.

Manual Trip Function: Allows testing of electrical contact function without tools, simplifying maintenance and diagnostics.

Fail-Safe Options: Models KP6, KP7, and KP17 feature fail-safe double bellows elements for enhanced safety in critical applications.

Environmental Resilience: Vibration and shock resistant, ensuring stable performance in dynamic operating environments.

Compact & Durable Construction: Space-saving design with fully welded bellows elements, ensuring mechanical and electrical reliability.

Versatile Enclosure Ratings: Available with IP30, IP44, or IP55 enclosures (KP Series), adapting to different levels of dust and water protection needs.

Broad Compatibility: Directly connectable to small single-phase AC motors (up to ~2 kW) and integrable into control circuits of larger motors, offering flexibility in system integration.
