The Coolspool 130 and 260 28V DC battery carts are designed to suit the requirements of a range of applications, from small corporate jet and medium size helicopter operators and FBOs to large fleet operators or FBOs supporting multiple DC business aircraft and requiring more capacity for frequent starts, compressor washes or avionics use.
A combination of high-discharge maintenance-free batteries, each of 130 Ah capacity are connected in series to provide 130 Ah capacity. Where increased capacity is required, the cart design allows a second set of batteries to be connected in parallel, thereby doubling the capacity to 260 Ah.
The Coolspool 130 and 260 are available in two nominal output voltages, 26V DC or 28V DC. Upper Fadec limits vary according to the manufacturer’s software and for this reason two versions of the Coolspool are available. All models of cart are fitted as standard with an internal 75A quickdemountable charger/power supply module providing rapid recharge of batteries.
Switching from ‘charge mode’ to ‘aircraft mode’ allows up to 75A of continuous power to the aircraft for extended avionics use and software updates.
Each Coolspool is fitted with a solid state voltmeter and charge ammeter, lockable heavy-duty push/pull emergency isolator switch, NATO lead set, charge lead and spare wheel.
The Coolspool range of battery carts is now recognized worldwide for the massive financial savings in fuel and maintenance they deliver to operators who have replaced diesel GPU’s with these silent maintenance and pollution free rechargeable mobile battery carts.
