AC&R OIL LEVEL REGULATORS

Maintaining oil level at required levels in compressors like reciprocating and scroll compressors is an important task to be performed in order to avoid damage to the compressor crankshaft, gears etc.

TK3+ monitors the oil level with the embedded electro-optic sensor and comprises a solenoid valve for oil filling and a relay output contact to give an alarm. It is compact, reliable and easy serviceable.

TK4 combines the established reliability and ease of installation of TK3+ with revolutionary connectivity capabilities which opens new and interesting usage scenarios for the product. TK4 in fact integrates a wireless near field communication protocol that allows users to easily interact with the oil level regulator to expand product’s features and enhance its flexibility.

TK4-MB combines the established reliability and ease of installation of TK3+ with revolutionary flexibility of TK4 extending its connectivity capabilities through the introduction of wired serial interface based on Modbus RTU protocol. Consequently, it is possible to have remote monitoring of the compressor pack even further effective letting it possible to optimize systems performances, to prevent and manage alarms and to elaborate accurate maintenance plans.

OIL LEVEL REGULATORS UP TO 46 bar

The TK3+ is designed to control the oil level in the compressor crankcase in order to avoid the compressor to run without oil and so improve its lifetime. TK3+ monitors the oil level with the embedded electro-optic sensor and comprises a solenoid valve for oil filling and a relay output contact to give an alarm.

HOW IT WORKS

The oil level is maintained at desired levels by specially designed control systems. Modern oil level controllers use electronic circuits
to achieve the objective. A typical electronic oil level controller that performs both functions of oil level monitoring and oil level
balancing is described below.

The system is compatible with most refrigerants like HFC, HCFC, and CO2.

The mounting onto the compressor is simplified by the dual pitch flange design. In case of different compressors fittings some
adapters are available to allow a quick and easy installation.

The electronic Oil Level Controller monitor the oil level in the compressors crankcase, and in case of oil lack is capable of directly try
to restore the oil or give an output signal.
They have been designed to be mounted directly onto various types of compressors.
The optical sensor monitors the level of the liquid by electro-optic infrared technology.

The electronics is designed to control the oil level of the compressor by activating a solenoid valve for automatic oil filling and
integrates also a separate alarm contact.
The oil level controller can be customized to function with various brands of compressors available worldwide.
