LHM are able to study your existing installation and through good fan engineering locally and in Germany offer improved replacements. Our unique ability to re-manufacture your fan and drive to best suit the improved design. This will ensure the best system efficiency.

To ensure operational safety, modern engineering tools will be used such as Finite Element Analysis (FEA) to test for dangerous rational harmonics and to avoid these.

Where energy savings are required, the offering will be accompanied by a lifecycle payback model to ensure that the capital spend is justified.

LHM has the capability to perform the complete range of the maintenance and upgrade requirements for fan installations. From the transformer to the motor, through the couplings and bearing to the fan. We have the competence to maintain the entire package.

LHM will design, construct, supply, install and commission to the OEM (Original Equipment Manufacturer) standard. Our technicians having gained vaulable experience locally have in most cases also been trained in Germany to provide OEM standard backup service.

Through our parts distribution agreement with TLT, we are able to supply OEM parts to the market, but there are also equipped to repair and upgrade all makes of fans.
