Water towers maintain a ready limited supply of water for communities in the event the water main goes down. Many water towers are used for emergency situations for the fire department to have water for fighting fires and for water fire suppression systems to have a supply of water for the emergency if it should arise.

HVAC Reznor Heating System LP Propane Gas Unit Heater – this Reznor unit heater provides heating for warehouses, garages, and other open spaces which can be heated with unit heaters. Unit heaters are ideal for big open areas which need heating without duct work being used to channel the air into the space. Sometimes these unit heaters are also used in mechanical rooms for protection of the other HVAC equipment and piping to prevent freezing conditions inside the mechanical rooms. The unit heater can be quickly installed and put into service in only a few hours once electrical service and gas service is provided in the location where the unit heater will be located. This unit heater is located in a remote camp site where electricity is available but natural gas was not available. LP or Liquefied Propane is trucked in to fill large LP Propane tanks located near the buildings which use these unit heaters to produce heat. A propane piping system and a series of propane gas regulators were installed and these unit heaters utilize the propane in the tanks being fed by this piping system. The regulators reduce the pressure from the tank to a usable pressure for the unit heater. Continue reading “HVAC Reznor Heating System – LP Gas Unit Heater” »
This is a photo of a diesel generator day tank for a diesel generator. The tank has floats inside that keep the fuel level automatically topped off in the tank so when the generator starts there is a fuel supply ready to go. As the generator consumes fuel the pump activates and resupplies the tank to keep the generator fueled and running. A pump will pump the fuel from the main storage tank to supply the day tank so the generator will have a days (give or take depending on the size of the generator and the load on the generator) amount of fuel to run under normal load. The controls for the day tank are more complex than other tanks which supply fuel for generators. An automatic day tank has alarms for the fuel level – alarms for both too low and too full alarms – and manual tests procedures for testing the pumps and fuel level floats.

Data centers use redundant systems for back-ups in case of an emergency. An HVAC chilled water storage tank adds an extra layer of redundancy to the process so if the chiller plants crash the chilled water storage tank or tanks will provide a small cushion of time to allow the operating engineers time to straighten things out or in a worse case scenario allow time for the servers in the data center to be transferred to another data center and shut down. Typically storage tanks will only allow for about 30 minutes to an hour before the data center floor reaches critical level and the servers need to be shut down. There are other applications for using chilled water storage tanks currently in use that save energy by storing chilled water in large thermal tanks for use during peak load times. During the day the stored chilled water is used instead of chillers. This reduces peak load saving money by utilizing the cheaper KW’s the utility company provides at night.
