Polar’s DC Generator solutions solve a myriad of obstacles that telecommunications companies face in the implementation of cell site backup power:
- A lack of space on site, our DC power systems are typically 1⁄2 to 1⁄4 the size of a conventional AC generator.
- Low natural gas supply pressure, Polar’s DC generators can operate at pressures as low as 4” of H2O (1 kPa) thereby eliminating long schedule delays and high costs associated with upgrading the utility natural gas supply pressure and flow volume.
- Reinforcing roofs to support the heavier AC generator sets, DC generators are 1/2 to 1/3 the weight of AC generators.
- Acquiring permits, as our DC generators incorporate low horsepower engines which ease the permitting requirements.
- Gaining fire marshal and landowner permission for fuel storage, we offer a choice of different fuels to satisfy location concerns and the quantity of fuel required on site is significantly smaller than that of our competitors;
- Acoustic noise, our power systems produce significantly lower noise than quiet AC generator systems.
- Cost of implementation, as our products cost less to procure, install, and operate.
The weight, cost, maintenance, and reliability issues of large battery banks and the current technologies offered by fuel cell companies are not a viable solution for extending the backup site beyond four hours. Our DC power systems are able to operate on all fuels including hydrogen, propane, natural gas, diesel, and bio-diesel and provide reliable backups reaching the goals of 72 hours.
Our goals include:
- Reducing fuel consumption by 30 to 70 % for most telecom sites.
- Reducing overall carbon foot-print by half.
- Reducing maintenance costs of the site.
- Eliminating redundant components like Power Monitoring Units or transfer switches.
- Offsetting high utility costs in peak period in grid powered sites.
- Increase the R.O.I. for Telecomm customers.
6 to 15 kW Back-up Diesel DC Generator Set
SMALL FOOTPRINT. Polar’s DC generator is considerably smaller in size than an AC generator. You can now backup sites that could not accommodate an AC generator. Smaller also means less cost for space leasing.
LONG RESERVE. 48 to 72 hour reserve. Polar’s DC generator can provide long reserve times because of very low fuel consumption. This generator should be the first choice for sites exposed to natural disasters requiring backup for weeks or months at a time (fuel consumption 1.02 gallon per hour).
LOW ACOUSTIC NOISE. <66 dBA @ 7 meters, and low vibration so as not to disturb the local residents or building landlords. Quieter than other generators with lower noise ratings. LIGHTWEIGHT. Up to 1/3 the weight of a comparable AC generator. Facilitates roof top installations.
CORROSION RESISTANT. All-aluminum enclosure with stainless hardware for low maintenance, and long service life.
SIMPLICITY. Transfer switch, rectifier, and starting battery are not required.
RODENT RESISTANT. Small animals can quickly destroy a generator set by gnawing on wires, fuel lines, radiator hoses, etc. Cooling air inlets and outlets have perforated aluminum screens to keep small rodents and large insects out. Stainless steel wire braid is placed over fuel and radiator lines for increased reliability and safety.
ADVANCED MONITORING. Remote diagnostics, control, and monitoring. Ethernet and RS232 standard, with optional SNMP.
SUPERCAPACITOR STARTER. Failure to start is the number one problem plaguing generator reliability. Polar’s unique design has replaced the starting battery with a Super Capacitor. Capacitors are more reliable and last longer than batteries (10-15 year life).
LONG LIFE. Controls and wire harnesses are designed to exceed a 20 year life. Higher grade, longer life electrical wire (UL 3173), weather tight connectors, gold plated connector pins on signal circuits. Controls and wire harness are easily replaceable.
6 to 15 kW Back-up LPG/NG DC Generator Set
SMALL FOOTPRINT. Polar’s DC generator is considerably smaller in size than an AC generator. You can now backup sites that could not accommodate an AC generator. Smaller also means less cost for space leasing.
LOW ACOUSTIC NOISE. <59 dBA @ 7 meters, and low vibration so as not to disturb the local residents or building landlords. Quieter than other generators with lower noise ratings. LIGHTWEIGHT. Up to 1/3 the weight of a comparable AC generator. Facilitates roof top installations.
