How do I decide which cooling unit will work for me?

This is determined by your Btu/h requirements.   To find your approximate Btu/h requirements, you'll need to follow this two step process.

1. Find the cubic capacity of the area to be cooled by multiplying its length, by its width,
   by its height. 
   
2. Take the cubic capacity found in step #1 and multiply it by 3 to find your approximate Btu/h requirements.

Example: If you're trying to cool an office that measures 20ft x 25ft x 9ft, your cubic feet would be 4,500.  Multiply that by 3 and your requirements are 13,500 Btu/h.   We would recommend any of our following portable cooling models:

        Water-cooled unit:    OceanAire PWC1811

        Air-cooled units:        OceanAire PAC1011, OceanAire PAC1211, or for extra capacity
                                             the OceanAire PAC1811.

NOTE:   You will need to adjust your Btu/h requirements when heat generating conditions impact the area to be cooled (for example: computers, telecommunication equipment, servers, dense occupancy, windows, etc).

What are the electrical requirements?

The Power Supply, Amps, and Nema Plug requirements for each of our portable cooling units are described on the appropriate Products page.   The table below provides additional information on electrical plug configurations and the required NEMA Plug receptacles. 

Plug Configuration	Receptacle	Plug Configuration	Receptacle
15A-125V	NEMA 5-15	20A-250V	NEMA 15-20
20A-125V	NEMA 5-20		NEMA 16-20
20A-250V	NEMA 6-20	30A-250V	NEMA 15-30
30A-250V	NEMA 6-30		NEMA 16-30
15A-250V	NEMA 6-15	50A-250V	NEMA 6-50

How is the unit vented?

This varies depending on whether you are using an air cooled or water cooled unit.  Some key points for venting are listed below. 

    Air Cooled Units

	An exhaust duct is required for air cooled units.  Most units require a 12" duct.  5-ton units require a 16" duct.
	When venting through a drop ceiling, space above the drop ceilings must be ventilated.
	Avoid kinks in the venting ducts.
	Our self-contained units automatically shut off and notify you when the condensate water reservoir requires emptying.

    Water Cooled Units

	Avoid kinks in the water lines.
	Assure adequate water pressure and drain facilities are available.
	When a hose-bib type connection is not available, units can be connected to a standard sink faucet using a faucet adapter which can be purchased at local hardware stores.

NOTE:   Temporary HVAC Cooling Systems are custom designed in the field.  Please contact us for specific information.

How do I determine which unit to use for an outdoor event?

Most outdoor events can be cooled with Temporary HVAC Cooling Systems or Evaporative Coolers. 
Contact us for recommendations on your event.

Who handles the delivery, installation and pickup?

We offer delivery, pickup and installation on all of our Portable units, on request.   A fee will be included for this service. 

Most of our units can either be picked up by the customer or delivered by us.  All that is required to operate some portable units is to roll it into place, plug it in, and turn it on!  Please look at the table below for available options.

What temperature will the unit cool to?

The operating temperature for each of the cooling units varies depending on the unit.  Review details of the cooling capacity for each of our portable cooling units on the appropriate Products page.

A fan is built into each cooling unit to adjust the airflow.  Once the desired temperature and fan speed have been set, the unit will operate automatically to meet your cooling needs. 

In order to maximize performance, we recommend that doors and windows in the cooling area stay closed.
