Coolspool 29 (AERO Specialties) Features and Specifications *
The Coolspool 29 is a versatile aircraft start unit designed for larger twin turbine aircraft and helicopters. It comes in two versions, offering nominal output voltages of 26V DC or 28V DC. This unit is particularly useful where additional amp/hour capacity is needed to maintain voltage under load, which is critical for ensuring reliable starts and protecting turbine life. The AERO Specialties Coolspool 29 is equipped with high-powered sealed lead-acid AGM batteries, an internal 3-stage charger for cell longevity, and a solid-state voltmeter to monitor battery voltage. Its design includes features like a corrosion-resistant aluminum case, a heavy-duty NATO connector, and a spring-loaded output cover, making it suitable for air transportation and on-board emergency use.
When compared to a 24V DC start unit of similar capacity, the Coolspool 29 provides significantly higher performance, resulting in faster spool-ups and cooler starts. This directly contributes to extending the turbine's operational life. Additionally, the unit is lightweight, with the 26V model weighing 28 kg and the 28V model weighing 29 kg, making it highly portable and practical for various aviation applications.
For added convenience and durability, the AERO Specialties Coolspool 29 28V Aircraft Portable Start Unit comes with optional extras such as a universal single trolley and a 4m NATO lead. Its robust construction, combined with features like shock-absorbent feet and a heavy-duty protective jacket, ensures that it can withstand the demands of regular aviation use while providing reliable power when needed most.
The Coolspool 29 price and features make it a very attractive option compared to similar power supply / starters available on the market.
