Temporary Cooling

Temporary Cooling – The Time to Plan Is Now!

As a facility manager, you know the importance of temperature control. Well-designed cooling systems keep employees comfortable and productive as well as maintain process output and efficiency.

If you have short-term cooling needs – for scheduled maintenance shutdowns, for supplemental cooling during hot weather, for special events – proper planning can save time and money, the same goes when planning for emergencies such as extended power outage or damage caused by a storm or fire.

Whatever business you’re in, you can use this Rental Temperature Control Planner to identify the temporary cooling equipment that best suits your operation, and make sure it’s available when you need it.

Just follow these simple steps and you’ll be ready to run without a hitch when short-term cooling needs arise.

Step 1: Decide what kind of cooling equipment you need – Your cooling equipment rental supplier needs to know what kind of system will serve you best. Short-term temperature control equipment comes in two basic varieties: fluid cooling and air conditioning.

Fluid cooling applies to industrial processes that use a heat exchanger or process tank to maintain the temperature of a liquid. The systems typically circulate chilled water, or for freezers and sensitive industrial processes, chilled brine is circulated. Applications include pulp mills, petrochemical and pharmaceutical plants, breweries, frozen food facilities and automobile factories.

Air conditioning involves maintain temperature moisture content, air movement and cleanliness of air in a defined space. Applications include hospitals, restaurants, office buildings, computer centers and factories, as well as special events like weddings, concerts and sporting events, especially when held in tents or other temporary structures. Another application is dense air injection a process of supplying chilled oxygen-rich air to maintain efficiency in a gas turbine or petrochemical refining process.

Step 2: Calculate the cooling load for your application – Before you rent temperature control equipment, you have to know how much capacity you need. Cooling load is measured in tons or kilowatts. Using the instructions below, you can help our equipment supplier calculate your cooling load.

Fluid cooling applications – This primarily involves rental chillers, sized by effective tonnage. Your in-plant chiller probably has its tonnage rating stamped on the manufacturer’s nameplate. If that information is not available, your supplier can calculate your cooling load if you provide the following data on your process or system:

  • Liquid temperature entering the application
  • Liquid temperature leaving the application
  • Flow rate of liquid(gallons per minute)

Air conditioning application – These installations typically use self-contained air conditioning units, or air handling units in conjunction with chillers. To calculate the chiller tonnage required for your space, your supplier needs to know:

  • Size of the space to be cooled(square feet and height of structure)
  • Space temperature and relative humidity desired
  • Expected ambient temperature and expected relative humidity outside
  • Number of people present
  • Kind of activity being performed
  • Type of structure and insulation
  • Heat-producing equipment used in the space
  • Air exchange requirement (if known)

NOTE: If you need temporary electric power for your cooling equipment, a good rule of thumb is to plan for 1.5kW of power per ton of cooling capacity. Your rental supplier can help you accurately plan your power needs.

Step 3: Know where to rent temperature control equipment – Your temporary cooling equipment is only as good as the supplier who backs it. As part of your planning, Finning Power Rentals has the equipment you need and a staff qualified to solve your problems and service the machines. We encourage you to make sure which ever rental company you hire is able to provide you with the following:

  • Have the tonnage or kW range your equipment requires
  • Able to deliver immediately or in emergency
  • Can deliver on weekends or holidays?
  • Will they supply hoses, flanges and ductwork for the cooling system?
  • Will they offer temporary power and distribution equipment?
  • Will they have a certified staff HVAC technician on site to start up the equipment?
  • Does their equipment meet all environmental codes and requirements?

Step 4: Answer the basics, save time and money – Before you have a need for temporary cooling, think carefully about the logistics. If you do, you will be able to get your rental equipment on-line in the shortest possible time. Consider:

  • Where will you put the temperature control equipment? The largest chiller modules are 8 feet wide, 50 feet long and 9 feet high. They require 8 feet of clearance on each side for proper airflow and service accessibility. The equipment must rest on a level, stable surface such as concrete, asphalt or hard-packed gravel. Buckled, broken or otherwise uneven surfaces nay require leveling.
  • If your application calls for air conditioning, how will you duct the air into your building or other structure? Consider doors, windows, outside air-intake louvers, or any opening that provides easy access to your existing air handling system. For tents and other temporary structures, your rental supplier can provide necessary ductwork.
  • If your application calls for fluid cooling requiring rental chiller modules, how will you route and connect temporary piping to your system? If you have no connections for temporary equipment, consider where to place them for easiest access in case your in-plant system should fail. Consider installing alternate flanged “T” connections in your piping system, with two-way valves to route temporary water flow to a rental chiller.
  • Where can I get temporary hoses, pumps, valves and flanges for my application? Your local rental supplier will be able to provide these accessories, or refer you to someone who can.
  • What happens if I need temporary power and rental cooling equipment? Finning Power Systems Rentals offers both cooling equipment and temporary power, with complete technical and temporary power, with complete technical support for both. By working with one supplier, you will save time and money and ensure smooth operation throughout your rental period.
