Heating, Ventilation and Air Conditioning


Large surface exhaust fan installation.

Modern refrigeration plant, cooling towers and water treatment plant.

Axial fans drive air through horizontal spray chamber air cooler.

Refrigeration machines in modern plant room.

3D graphics from VUMA network model.


Ventsim Visual can rapidly build and display ventilation models by importing data from existing mine planning or CAD software; models are built in 3D, and can be rotated, zoomed and animated in real-time.

Ventsim training can rapidly skill personnel in the use of the many advanced features of the program; training can be performed in formal groups, or one-on-one in a mining environment.

Existing mine workings and 3D solids can be imported into Ventsim Visual to provide a stunning 3D visualisation of your ventilation network; up to 70 different types of ventilation data can be viewed, coloured and animated.

All aspects of mine ventilation can be modelled in Ventsim Visual, including heat, humidity, airflow, fan pressures, costs, regulator pressures, diesel particulates (DPM), and recirculation.


Crisp-Air’s cold plasma (non-ozone-forming negative ionization) technology for air filtration magnetises the fine particulates to cause clusters, which either lose suspension or become large enough to be captured in filtration systems.

Crisp Airgineering™ provides air-filtration systems to capture respiratory dust, which are particles less than 10µ that should be reduced in order to improve the workplace and equipment reliability.

Crisp-Air provides air-filtration systems to capture respiratory dust, or those particles less than 10µ, which should be reduced in order to improve equipment reliability and working conditions.

Crisp-Air’s self-purging twin filter assembly for air filtration of control and switchrooms.

Crisp-Air provides dust prevention and removal in site sheds, control and switchrooms.


Duraduct offers a variety of tubes and piping for mining use.

Our lockseam tube is used for ventilation ducts, electrical conduit and cable channels.

Duraduct provides a lockseam tube for use in concrete column forms and other building construction applications.


JP Jensen Ventilation is represented by agents around the whole world.

Long experience and major research work enable JP Jensen Ventilation to produce fabrics with minimal elongation of the base fabric.

JP-Superjoint - a patented coupling for ductings, to ensure straighter airflow and airtight systems.

JP Jensen Ventilation always delivers complete ductings; ready to hang up.

Together with bends, Y-branches, T-branches and cones, which are made out of extremely solid fabrics with welded seams, JP Jensen Ventilation offers a complete and dependable ventilation system.


Ventstop Ventilation Control Unit (VCU) stopping.

Passline Overhead Protection Unit (OPU) system.

Passline is suitable for most vertical, dumped or inclined shafts and raise bore holes.

The Passline overhead protection system has been designed to enhance the safe working parameters of personnel and infrastructure.

Shaft Plug Void Sealing System (VSS) provides emergency and short-term sealing of an intake or exhaust shaft.


Mine Ventilation Services (MVS) provides subsurface ventilation and environmental engineering.

MVS has been providing ventilation engineering services and computer software to the mining and tunneling industries since 1983.

MVS specializes in diesel particulate matter (DPM) studies and laboratory analysis.


MAS 1000 climate-control unit for roof-mount installation on mining equipment.

Our MAS 350 unit climate-control unit for mine equipment.

A haul-truck cab with an MAS 361 climate-control unit.

A MAS 1300 climate-control unit on an electric blasthole drill.

An electric shovel with MAS 1500 climate-control units.


POLYDUCT Positive and Negative Pressure Systems are cost effective, modular ventilation ducting that will last the life of your mine.

4-Way Sections complete with directional valves to control air flow.

Polyethylene is an excellent material for Fan Silencers, by using a high tech sound foam barrier, we are able to maintain an overall width of less than 50mm.

Self Regulating Fan Covers are a simple configuration that bolt to the fan flange and automatically opens or closes with air flow from the fan.

Fire Retardant Anti Static Detonator Boxes have mines department approval in WA and QLD


Protan specialises in the design, production and manufacture of webs intended exclusively for use in ventilation ducts.

A stable yarn is important when you manufacture flexible ventilation ducts: it helps to maintain shape, gives better air transport and less turbulence.

Protan supplies different types of steelhooks.

Protan's mounting system has longitudinal suspension with welded PVC eyelets along the entire ventilation duct, which ensures optimal fastening and longitudinal stretching of the duct.

Both VF and LP coupling models also come in two parts for easy installation of large diameters.


Axial mine ventilation fan, vertically arranged and removable.

Removable axial mine fans with motor inside the fan hub and with blade adjustment system.

Axial fan with a power consumption of 13,5 MW.

Formula 1 – wind tunnel.

Axial Flow fans for the “Bad Godesberg” road tunnel (2 km length).
