We are a major supplier of self-contained portable jobsite heaters used throughout the world. Introduced in 2001, the Duplex-Heat® plays a significant role in providing clean, safe heat to remote locations in the oil and gas, mining, construction and remediation industries, as well as in many others.
HAFE manufactures and supplies the Ultra Heat portable heater for temporary worksite heat, concrete curing, equipment pre-heating, wellhead thawing, plant maintenance, pipeline construction, winter painting, industrial tank coating and a host of other applications.
Diesel-fired heaters
Indirect combustion through Ultra-Heat's twin 505,000BTU per hour diesel-fired heaters ensures that only clean, breathable heated air enters the work area. Each of the two heater units has standard 16in diameter flanged outlets that allow up to 110ft of flexible ducting to be connected to each unit, to further ensure that combustion by-products from the heat exchangers are exhausted safely away from the heated area.
Also available on the Ultra-Heat is an optional combustible gas detection system, which will detect the presence of explosive gasses and then power down the Ultra-Heat, as well as operate a visual strobe warning alarm before gas accumulation can approach potentially explosive levels.
custom-designed ventilation, cooling and heating systems for mining applications throughout the world. The company manufactures and installs centrifugal fans, fixed and variable pitch axial fans, mixed flow and auxiliary fans, as well as a full turnkey service from design to commissioning.
Many of the best known names in mine ventilation are now included in the HAFE organisation, including Alphair Ventilating Systems and HAFE Babcock. The company can provide spares, support and upgrades for virtually any main ventilation fan anywhere worldwide.
Mine ventilation engineering and equipment
HAFE understands the rigors and demands its equipment will be subjected to by mining applications, as well as the technologies and economy of the industry. The company has a working knowledge of various regulatory environments and best practice guidelines from different countries, and its experience covers some of the deepest, coldest and most remote mines in the world.
In addition to fans and associated heating and cooling systems, HAFE supplies ancillary products such as dampers, controls and instrumentation, ducting and drives, including highly efficient fluid drives. The company can organise and manage your entire project from civil engineering groundwork to the handover of a fully tested installation, or simply deliver products for your own engineers to install.
Economical and energy-efficient mine fans
HAFE's experience, engineering skills and constant investment in research and development enables the company to make fan and ancillary equipment of exceptional energy efficiency and reliability, and outstanding cost-effectiveness. The company has a proven record of significantly reducing lifetime operating costs for mine operators.
Mine Ventilation and Refrigeration
leaders in mine ventilation, refrigeration and cooling practices; measurement and control of underground pollutants (dust, diesel, methane, radiation etc); energy optimisation and energy recovery, computer modelling and software for ventilation and cooling networks.
MINE VENTILATION, REFRIGERATION AND AIR-CONDITIONING SYSTEMS
HAFE provide a comprehensive service from conceptual investigations, through technical feasibility studies and the analysis of alternative ventilation and cooling distribution systems, to selection of the optimum system, preparation of detailed engineering design specifications, estimating and project execution and management, for existing mines and new projects.
HAFE strive for energy efficient systems making optimum use of energy recovery devices (Pelton wheel turbines, three-chamber pipe feeders, hydropower etc)
MINE HEALTH AND SAFETY, FIRE PREVENTION AND PROTECTION
HAFE have considerable experience in the control of underground pollutants and in fire engineering, having contributed significantly to numerous research and investigation programmes around flammability of materials, fire engineering, fire fighting techniques and escape and rescue strategies.
Ventilation ducting
HAFE ventilation ducting is constructed of woven polyethylene fabric extrusion-coated with a low-resistance film. It is available in a range of diameters and lengths. HAFE can provide different styles of ventilation ducting, including straight lengths, reducing pieces, concertina lengths, bi-vent lengths and bi-vent transition pieces.
Ventilation duct fittings
In addition to its range of standard ventilation duct and fittings available in six sizes, HAFE also offers other speciality pieces including, but not limited to:
- Concertinas
- Fan adapters
- Parachutes
- Shaft tarp
- Bi-vent duct and fitting
- PVC duct
- Fire-resistant (FR) duct
- Anti-static (AS) duct
- FRAS PVC duct
Air-conditioning for highly ambient mine sites
HAFE supplies high-ambient cooling, temperature control, HVAC units and solutions; portable and fixed electrical houses, and substations; design and establishment of production lines; as well as continuous plant upgrades.
HAFE's integratable air-conditioning units (aircons) are designed to operate in adverse conditions, providing reliable cooling for industrial enclosures with high-temperature environments of up to 65°C. Optional features make the units versatile and the structures are easy-to-maintain, with all spare parts readily available.
Aircon units for mining vehicles and machines
HAFE offers custom air-conditioning solutions for mining vehicles operating in temperatures up to 55°C. Mine vehicle aircon units are developed to be reliable in high-temperatures and humid, dusty environments, and able to withstand shocks and vibration.
All HAFE temperature control units are performance tested in HAFE's climate-control room. The equipment is also vibration and EMC-tested, where necessary, to ensure optimum performance and compliance with the relevant specifications and procedures.
Climate-control rooms and substations for plants
HAFE offers climate-control rooms with electrical houses (E-houses) or substations, designed to meet clients' carbon footprints.
The large, movable compartments are custom-built to last for 30 years* in extremely adverse environments and are ideal for housing electrical switchgear panels (*enclosures are manufactured to SS316, SS304 or 3CR12).
HAFE's HVAC solutions for plants and buildings are offered as normal packaged and split units, chiller solutions, and thermal ice and hot water storage systems.
The company supplies the latest technologies for plant upgrades, including robotic grabs for material stacking, unmanned shuttle cars for material transfer, trailer solutions for distributing parts in production lines and mobile and fix platforms for production assembly lines.
MAIN MINE VENTILATION FANS
HAFE provides today an extensive range of solutions for mine ventilation axial and radial fan arrangements, tailor-made and innovative, working as exhaust ventilation or in pressing ventilation mode, arranged horizontally or vertically and both, above or underground. HAFE will assist you in the selection, planning and calculation of the most suitable solution.
AXIAL-FLOW AND CENTRIFUGAL FANS FOR POWER PLANT APPLICATION
The various designs and sizes of HAFE heavy duty fans are used in power plants. The decision for the application of HAFE-Turbo axial fans for coal fired boilers as well in mono-units up to 850MW (only one primary, one forced draft and one induced draft axial flow fan each per boiler unit) has been fundamentally influenced by the high availability and reliability.
HAFE-Turbo were also pioneers in the development of the first Flue Gas Desulphurizing (FGD) axial flow fans on the wet, saturated clean gas side behind the scrubber.HAFE- Turbo are actively involved in the international cooperation in the CO2 capture process.
INDUSTRIAL FANS AND BLOWERS
Centrifugal fans and axial impulse-type fans are ideal for all industrial applications. Optionally hard-faced for abrasive, dust-laden media or in stainless or rubberized versions for use with corrosive gaseous fluids with peripheral speeds up to 270m/s.
