Cool Cell Models

Cool Cells for Electronic Equipment


These enclosures are fitted with multiple  cooling reservoirs and large or multiple radiators to absorb and  dissipate high heat loads.  Equipment can be mounted in 19″ or 23″ racks  or mounted directly to cold plates touching to the cooling reservoirs.






Standard Plenum Series: Small

The standard plenum series Cool Cells are sized for monoblock car size  group 27 or group 29 batteries as well.  They perform well in all  climates and weather conditions where subfreezing temperatures are  common.  For extremely cold conditions a supplemental electric heater is  recommended.  Pole mounts can be purchased with these as an option.

The radiator lid of the enclosure overhangs the box below  to increase surface area and cooling. The sides and back of the  enclosure are also radiators.  The radiators are plumbed to multiple  internal  reservoirs which absorb heat from the electronics which  moderates the enclosure temperature.  Equipment racks can be  incorporated into the design as needed.  When batteries are part of the  package a hydrogen vent is included. 

Why cooled enclosures?

Many electronic devices are built to operate when their temperatures are below:

 55 ⁰  - 130 ⁰ F 


60 ⁰  - 140 ⁰ F

Such equipment must be cooled since a plain box will easily exceed such temperatures even in mild climates.


This High Flux Cool Cell enclosure contains the air monitoring pump and  associated electronic equipment used to monitor air quality at Mono Lake  in California.  It has four 12 sq. ft. radiators and 4 internal cooling  reservoirs to maximize surface area and cooling effectiveness. The  enclosure was mounted on a pressure treated wood skid so it can me moved  and relocated with a minimal environmental footprint. 


 Each enclosure houses 3 stacks of GNB 100A39 batteries.  The batteries  are used to store the electrical power produced by the solar array.  The  enclosures are fitted with the patented passive Convective Hydrogen  Vent which eliminates any explosive hydrogen gas produced when the  batteries are charged.  The system was designed to provide several days  of autonomy without any sun. 


This Cool Cell has a large capacity and is economically priced. It's intended for hot climates without harsh winters. These battery saver, cooled enclosures are not freeze proof and should not be used if total freeze up is possible. The usable interior space is 46” w x 23” d x 13” h. and will hold four 8G8D size batteries. It’s fitted with a 2” Convective Hydrogen vent which extends battery life and has a 2” FPT conduit fitting on both ends. 


This pole mounted mini Wattbox has 2 compartments.  The top section is  passively cooled and can hold two 12 volt 100 Ah batteries.  It has a 1”  convective hydrogen vent.  The ventilated bottom compartment is  accessed through a drop down panel and has removable mounting panel  which can hold charge controllers, circuit breakers or other wiring  devices. 


This model will hold 2 ea. group 29 batteries.  It is fitted with  uni-strut channel on the back side and is intended for pole mounting. It  has a passive 1” Convective Hydrogen vent to safely vent any hydrogen  produced during charging.  Conduit access is through a 2” FPT fitting on  both sides of the enclosure. Its’ insulated with 2” of Styrofoam.  (R-10) 


 This Cool Cell holds 4 group 27 100Ah batteries configured in a 48 volt  string.  It provides back up power in a utility switch yard. During an  outage it maintains the communication link with the central office. 


This economical Cool Cell is fitted with 3 fixed shelves. It will hold  up to 12 group 27 or 29 batteries.  It has an optional wiring harness  with positive and negative busbars for 3 strings of batteries at 48  volts or 6 strings at 24 volts. Approximately 5” of space is available  above the batteries for servicing.  For hydrogen safety it has a 2”  Convective Hydrogen Vent. 


This enclosure is fitted with 6 pull-out battery trays. (500 lbs. cap.  Ea.)  It will hold 6-48 volt strings of 125 Ah batteries. Its” used  primarily for stand by power in telecommunication and utility  applications where easy access to the tops of the batteries is required 


This Cool Cell has 7 vertical fin radiators mounted above the  enclosure.  Each radiator is plumbed to a 20 gal. reservoir suspended  below inside.  The individual reservoirs maximize surface area to absorb  heat.  The radiators on top are  plumbed to a common expansion tank   which makes filling easy.   The equipment was placed on the floor of the  enclosure under the reservoirs.  Heated air convects up between the  reservoirs, is cooled and returns to the floor to cool the electronics.   This Cool Cell and Air monitoring System was trailer mounted and moved  around the Joshua Tree National Park.   The enclosure and electronics  stayed at least 5 degrees C. below the ambient temperature even when the  daily high was 40 C. The internal heat load was a continuous 150 watts.
