INT280 Oil Level Regulator

The KRIWAN INT280 oil level regulator is a high-precision solution for monitoring and maintaining the correct oil level in refrigeration compressors. It ensures optimal lubrication, preventing compressor damage and enhancing system efficiency, especially in multi-compressor systems with reciprocating or scroll compressors.

Unlike traditional mechanical float switches, the INT280 uses an infrared optical measurement principle, analyzing light refraction to accurately detect oil levels. This eliminates errors caused by oil viscosity and ensures reliable, maintenance-free operation. A self-adaptive filling algorithm dynamically adjusts refilling cycles based on operating conditions, optimizing oil distribution and preventing unnecessary refilling.

The INT280 features multiple connectivity options, including direct cable connection or M12 plug, allowing flexible integration into different system configurations. Alarm and status LEDs provide clear operational feedback, while an integrated sight glass enables visual oil level inspection.

Designed for various installation scenarios, the INT280 is available with 3- and 4-bolt flange options and supports different adapter types for seamless compatibility:

Supporting 24V AC, 115V AC, and 230V AC, the INT280 is suitable for various power supply configurations. It is available in two pressure variants:

Additionally, the KRIWAN INTspector app allows parameter customization, diagnostics, and real-time data logging. Operating data, including oil fill cycles and compressor shutdown events, can be accessed locally or integrated via Modbus Gateway into the plant’s control system.
