Improving MRO In Cold Weather

A guide to products designed for improving MRO operations in below-freezing temperatures.

1. Keeping Mechanics Warm

Product: IcePlate Safety Vest

Qore Performance

Specifications: The IcePlate Safety Vest from Qore Performance is a wearable piece of safety equipment that MRO workers can use to regulate body temperature and stay hydrated while working in extreme temperatures. The product combines a safety vest, tool belt, hydration bladder and the company’s IcePlate water bottle, which holds three liters of water that can either be frozen—to keep workers cool in hot temperatures—or heated—to provide 3-5 hr. of heating via thermal conduction. The product already is in use at a variety of drive-through restaurant chains as well as with airlines such as United and JetBlue.

2. Waterless Engine Wash

Product: Cyclean Dry Ice

LHT Cyclean Dry Ice

Specifications: Lufthansa Technik’s (LHT) new Cyclean Dry Ice system allows washing of aircraft engines in below-freezing weather thanks to its waterless washing procedure. Cyclean Dry Ice uses a mobile blasting system to shoot dry ice pellets into an aircraft engine, which dislodges dirt without leaving any residue since the pellets transition to a gaseous state. LHT says the system can clean engines of any size or height in 30 min., which results in quicker turnaround times as well as water savings. The system will go on the market in 2019 and be offered on either a long-term lease basis or as a full service performed by LHT.

3. Ice Prevention

Product: TKS Ice Protection System


Specifications: The TKS Ice Protection System from CAV is an anti- and de-icing solution for aircraft wings. The system works by dispersing an ethylene glycol-based fluid from laser-drilled titanium panels, which are mounted on the leading edges of a wing, horizontal and vertical stabilizers, and wing strut. The fluid works as a freezing-point depressant as it flows over the entire chord of the wing, preventing ice from forming. According to the company, the system allows aircraft to be certified for continuous operation under all federal aviation icing regulations. CAV works with more than 20 aircraft OEMs, and the company says it has installed TKS Ice Protection in more than 30 aircraft models.

4. Accurate Tooling in Extreme Cold

Product: Digital Torque Multipliers

Advanced Torque

Specifications: The use of hydraulic torque multipliers outside the hangar environment can get dicey when temperatures dip below freezing. The hydraulic fluid they use can change viscosity in cold temperatures, which affects accuracy and operations. Advanced Torque Products’ digital torque multipliers prevent this problem by virtue of their completely mechanical operation, which is not affected by climate extremes. According to the company, its digital torque multipliers have an operating temperature range of 0-140F and have been chosen by the U.S. military for operations in extreme temperatures in Afghanistan.

5. Improving Cold Start Performance

Product: Eastman Turbo Oils


Specifications: Cold temperatures present problems for the oils used in aircraft operations. They can make oil more viscous, which could result in damage to bearings, static discharges in generators and the inability to start engines or APUs. According to Eastman Chemical Co., the aviation industry has recognized that lower-viscosity oils, such as its Eastman Turbo Oil 2389 and Eastman Turbo Oil 2380, can help resolve issues related to APU cold-temperature starts. Eastman says these oils improve performance during cold starts, providing more reliable aircraft operations.
