- NOTE **
- NOTE ** Mars Air Doors offers a complete line of Air
- Curtains providing the benefits of temperature
- control and environmental separation. Models are
- offered in a commercial and industrial design and
- can be configured with heat. Heated units include
- gas, electric, steam and hot water coil models.
-
- NOTE ** A typical installation is over a building's
- exterior door or window opening. They provide
- excellent protection at reducing a building's
- heating and cooling costs when these exterior doors
- need to be opened. At the same time, they repel
- gusts of wind and minimize the entrance of
- windborne dust, fumes, pollutants, and flies.
- Additionally, they help to expedite the flow of
- traffic from one work area to another or in and out
- the building, by providing an unobstructive view of
- the opening. This section covers the industrial
- part of their product line: "Standard," "High
- Velocity (HV)," "Extra Power (EP)," "Windguard
- (BD)," "Extra High Velocity (EHV)," and "Extra High
- H Velocity (EHH)" models. See their other Section
- 15831 for commercial models.

- 2.2 MANUFACTURED UNITS
- NOTE ** Retain the following paragraph if specifying Mars
- "Standard," "HV" (High Velocity), or "EP" (Extra
- Power) Model units. "Standard" and "HV" models are
- used over freezer and cooler doors to reduce
- humidity and ice buildup, sealing in cold air and
- saving energy. They are also used over
- receiving/service entrances for both climate and
- insect control.
- NOTE **
- NOTE ** "Standard," "HV," and "EP" models are used for
- climate control and energy conservation; installed
- inside of buildings with high ceilings, they bring
- wasted hot air from the ceiling over the door
- opening and to the floor level. This eases the
- load on the heating system. These models are also
- available heated with electric coils, gas, steam,
- and hot water single or double row coils.
- NOTE ** "Standard," "HV" (High Velocity), "EP" (Extra
- Power), and "Windguard (BD)" models are all used
- for the same reasons. The height of the door
- dictates which model to use. All four of these
- models are available in gas, electric, steam, or
- hot water coil forms of heat. "Standard" and "HV"
- models can also be used over cooler and freezer
- doors. Units can be mounted either inside or
- outside of the building. If using a heated model,
- it must be mounted inside the building.
- NOTE **
- NOTE ** "EHV" and "EHH" models are for insect control only.
- They are available as unheated models only. They
- can be mounted either inside or outside of the
- building.
