What size of unit will I need?

This depends on the door size but also the room size

How Does an Air Barrier Work?

By re-circulating internal facility air and forcing it across an opening, Enershield Air Barrier technology creates a 'Virtual Door'.

How much electricity is required does a nitrogen generator need?

Membrane generators do not need electricity which makes them ideal for explosion-proof locations. If they include an oxygen analyser, they need minimal current rated at 120 VAC, 0.25A. The standard PSA nitrogen systems have an electrical rating of 120 VAC, 2.0A.

Nitrogen generators express purity of nitrogen as 100% minus the percent of oxygen remaining in the gas stream. Why is that?

In air, oxygen is the most reactive gas and is present in significant volume. The balance of gases are either trace or in the case of argon, not reactive. In addition, oxygen content can be easily and directly measured with an analyzer. Therefore, a 99% nitrogen stream is really 1% oxygen and 99% nitrogen and other gases.

How Does Evaporative Cooling Work?

Based on the simple principles of evaporation, hot and dry outside air is pumped through water soaked pads called Chillcel® pads.  As the air blows through the Chillcel pads, the water is evaporated and the heat in the air is absorbed, which lowers the air termperature.  A fan then pushes the cool air through the ducting system into the building.

Can I use Evporative Coolers to remove production smells/unpleasant odours/smoke from my facility?

Yes you can.  With no recirculated air (as regards traditional refrigerated systems), evaporative cooling is the best solution for industrial plants, especially in production and packaging areas. Keeping doors or windows open (or using an exhaust fan), the fumes, germs, CO2 and odours are drawn outside while the cooler brings in 100% fresh air.

Is Evaporative Cooling a Safe Solution

The water in an evaporative cooler circulates at a naturally cool temperature therefore potentially dangerous organisms do not present a risk. The unique design and process controls, prevent water stagnation, whilst the plastic and stainless construction avoids corrosion. A constant supply of naturally cooled air is supplied by the coolers without using refrigerants. 

Does Evaporative Cooling Help Improve Indoor Air Quality?

Evaporative air conditioners (coolers) are excellent for health
• They supply 100% fresh, filtered air into your building that is not recirculated, improving Indoor Air Quality (IAQ) of the space, supporting customer and staff well-being
• They remove unhealthy pollution from your indoor environment
• They provide basic moisture that the human body needs
• They remove static electricity; they can assist in reducing the effects of illnesses such as asthma.
