1.0 INTRODUCTION

• The Sigma ‘M’ Series Air Conditioning units have been designed and manufactured in Australia for mobile and stationary applications in the harshest of environments. High ambient conditions and/or vibration together with heavy particulate fallout are often encountered on mining and industrial areas.
• The Sigma ‘M’ Series have been developed over many years and are purpose built for these conditions. They can be supplied in a variety of configurations to meet any application such as a selfcontained package or as a split system with either roof or ceiling mounted fan coil (cooling) units.
• Four capacities are provided within the range and depending on requirements either 7kW, 20 kW or 25kW of cooling is available. Air can be discharged and returned through the roof mounted evaporator base or sides. Fresh air pressurisation is provided by means of fan/filter units integrated with the evaporator or mounted separately. The units are designed using the highest quality components for maximum life and reliability.
• They include special features such as stainless steel construction, return air filters, electric element heating, semi-hermetic compressors and easy access for service.
• In all, the units are designed to continue working, providing comfortable conditions for both operators and electronics of mining and industrial equipment thereby resulting in minimum downtime over many years. Due to environmental problems with previous commonly used refrigerants, this series has been designed for use of ozone friendly HFC134a in standard applications.
