Babcock Wanson offers a complete range of purpose built Process Air Heaters for both direct and indirect air heating. HTV-N HTV-N is an indirect fired fresh or recirculated air heater which utilises an externally mounted process air fan. Air is heated by contact with the combustion chamber and the second pass tubes to reach the desired temperature. An optional economiser for very high efficiency operation is available. This method of operation provides effective heat transfer, reliable operation and low fuel consumption over an extended life. MIXBLOC The MIXBLOC direct fired airstream heater is designed to provide high temperature air with no flue gas losses. MIXBLOC can operate using the process air flow or an independent combustion air fan. Burners are constructed from multiple “V” elements assembled in differing configurations to suit the required heat output and process ductwork design. GASAIRBLOC High process air temperatures are provided by the GASAIRBLOC Heater. The Heater is direct fired using either gas or liquid fuels with independent combustion air supply to achieve air discharge temperatures of up to 1200°C. With direct heat input and no flue gas losses, the GASAIRBLOC provides very efficient operation for processes that need high temperature and can work with the clean products of combustion entrained with the heated air flow strea

HTV-N Indirect process air heater Output range: from 90 kW up to 7 MW HTV-N is Babcock Wanson’s range of indirect fired process air heaters constructed to provide clean hot air at up to 350°C and supplied complete with fully matched burner for gas, LPG or oil firing. The perfect solution where high temperature air is required for processing needs. Flexible operation: High efficiency: HTV-N are custom designed to suit the specific demands •• Fixed air flow for accurate control •• Fully modulating burner control of each installation. Process air flow range between 1,000 •• Air by-pass options available...

Solutions for your application Special application HTV-N for Drying Application - Indirect air heating HTV-N are perfectly suited to heating process air streams with very high moisture content or entrained water vapour. The Babcock Wanson HTV-N Process Air Heating solution simplifies and reduces the total cost of installation and operation when compared to traditional indirect heating methods. Particularly when planning new installations, the reduced space demand and ease of operation greatly reduces overall cost and normal operating maintenance demand. HTV-N offers a simple method of providing...
