Temperature-Independent Lubrication System

Shield TGL is a complete lubrication system for challenging environments with high temperature fluctuations.

Shield TGL provides hassle-free lubrication from 1 to 12 months via the digital TGL control unit. It takes into account the ambient temperature and then calculates the required quantity of gas for constant and reliable discharge.

Shield TGL Lubrication System

Single-Point Lubrication

Shield TGL was developed for single-point lubrication in areas with considerable temperature variations, such as outdoor installations. It can be used on fin fans, electric motors, pumps and blowers, at temperatures ranging from -20°C to +60°C (-4°F to +140°F).

The lubrication system is protected against dust and water jets (IP 65), subject to correct assembly. Shield TGL consists of a reusable control unit, a Shield TGL lubricant cartridge filled with grease or oil, and a protective cover.
