High Efficiency Heating with Schwank Radiant Heaters from Devex

High Efficiency Heating for Medium to Large Facilities
Schwank Gas Radiant Overhead Tube Heaters

Case Study: Liebherr Erskine Park, NSW Manufacturing Facility

Background: For several years now, Liebherr has standardised facility heating using only Schwank heating solutions. Schwank Gas Radiant Overhead Tube Heaters were therefore selected as the preferred choice for heating the Erskine Park location.

The Erskine Park, NSW facility was newly built in 2012 with a number of workshops designed for the repairs and maintenance of crane machinery. With over 80 staff in this facility, ensuring comfortable working conditions throughout the year was of utmost importance.

The team at Liebherr, Erskine Park wanted a solution that not only satisfied staff comfort levels, but would also conserve energy and reduce long-term running costs. Liebherr-Australia commissioned Thiess, a leading construction and services contractor in Australia for the construction and redevelopment of the Erskine Park facility. Additionally, the exclusive distributor of Schwank heaters in Australia, Devex Systems, worked directly with Liebherr and Thiess to co-ordinate, design and oversee the installation of this project.

Schwank Gas Radiant Overhead Tube Heaters

Heating the Facility: calorSchwank Gas Radiant Overhead Tube Heater & The ThermControl Plus Controller

The size of the space heated with high efficiency Schwank Gas Radiant Overhead Tube Heaters was approximately 2600m2 with a mounting height between 9.5m-12m and 4 zones. Air changes were estimated around 1.5 per hour and the estimated heat loss of the facility was approximately 580 kW.

Twelve calorSchwank tube heaters (5 x 40U & 7 x 30U) were specified in the design for this application after taking into consideration the large enclosed area of the space that required heating and its ceiling height. The designed comfort setting for the area being heated was 16®C as measured by a black bulb.

A single Schwank Thermal Control Plus M4 controller applied to 4 heating zones at the Erskine Park facility was used to control the heating system. It was also set up to control the Ridge Ventilator, enabling appropriate ventilation and the proper disposal of combustion gases when the burners were running.

The calorSchwank ensured low running costs and a fast pay back as the heaters were required to run for long periods of time. The radiant heat factor of the calorSchwank was extremely high sitting at 70% and its modulation capabilities allowed for better overall control of the system and higher efficiency. The design of these heaters helped to minimise the amount of convection heat thereby achieving a high radiant factor and improving the efficiency.
