Locating the batteries outside creates more space inside and improves battery access. Cool Cell structures range in size and can accommodate many industries & equipment needs.
Zomeworks has sold to a number of utilities, including Tucson Electric Power, Public Service Co. of NM, & Sacramento Metropolitan Utility District. These utilities are primarily interested in standby battery storage in case of a power outage. The following Cool Cell models would be appropriate for this industry.
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 4 battery Cool Cell Enclosure is fitted with a side box for related electrical components which could include charge controllers, circuit breakers, or other electronic equipment. It's generally not good practice to mix batteries with electronic components especially if a spark or arch is possible. Batteries produce potentially explosive hydrogen gas when charged. Even sealed VRLA batteries are a threat. All battery Cool cell have a hydrogen vent system.
Like the Utilities Industries, telecom's want standby battery storage. In addition, they need storage for their electronics. This combination will generate more heat which takes a different Cool Cell configuration. Zomeworks has supplied Cool Cells to Sprint, Qwest now Century Link, Bell South now part of Verizon. The following models apply to this industry.
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. It's used primarily for stand by power in telecommunication and utility applications where easy access to the tops of the batteries is required
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.
The radiator lid of the enclosure overhangs the shadow of 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.
Many private and commercial photovoltaic installations need temperature regulating enclosures for their storage batteries and inverters. Zomeworks initially designed the Cool Cell for such applications and has supplied these enclosures for over 20 years.
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 Cool Cell has a large capacity and is economically priced. Its’ intended for hot climates without harsh winters. It’s not freeze proof and should not be used if total freeze up is possible. The useable 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 and has a 2” FPT conduit fitting on both ends.
