Do you need an actuator for a hot or cold place? That’s a big job. At Jimi (Jimi Technology Co., Ltd.), we make actuators that can work in many tough spots. We know what you need and how to help.
Let us tell you why picking the right high temperature actuator or low temperature actuator is so important. If you use the wrong one, it can break, get stuck, or even leak. That means lost time, trouble, or even danger. Let's learn how to stay safe and smart with your choice.
Why Extreme Temperatures Are a Big Deal
Extreme heat or very cold can do bad things to machines.
- High heat actuators can get too hot. Metal parts can bend or get soft. Seals can melt.
- Low temperature actuators feel the freeze. Some parts crack or get stiff.
- Both cryogenic actuators and harsh environment actuators live in the tough zone.
- If you pick the wrong actuator, it might fail. When that happens, work stops. Or worse, something breaks and people might get hurt.
“Extreme temperature” means anything too hot or too cold for normal machines. For example:
- Hot: Over 150°C (like in a furnace valve or steam turbine)
- Cold: Below -40°C (like cryogenic systems or cold storage automation)
What Happens to Actuators in Hot or Cold Places?
Let’s look at what can go wrong:
- Materials
- Thermal expansion: Metal or plastic parts change shape when hot or cold. Things can stick or not fit right.
- Material degradation: Softening, cracking, or melting can happen.
- Corrosion: High temps make rust worse.
- Some materials work better than others. For example:
- Use austenitic stainless steel in cold
- Use superalloys in high heat
- Seals and Gaskets
- Seals keep oil in and dirt out.
- In hot spots, elastomer seals (like FKM, FFKM) might melt—use metal bellows.
- In the cold, PTFE or silicone can stay soft.
- Lubrication
- In hot: Oil breaks down fast or burns away.
- In cold: Grease gets thick and sticky.
- Pick the right lube:
- Synthetic oils stay slick in the cold
- Dry film lube (like MoS2) helps in the heat
- Electronics & Wiring
- High heat can break wires or chips in electric actuators.
- Cold can crack insulation or make poor connections.
- Mechanical Parts
- Bearings might crack in cold or wear out fast in the heat.
Table 1: How Extreme Temperatures Hurt Actuators, and How We Solve It
| Problem | What Happens? | Jimi Solution | Success Story |
|---|---|---|---|
| Seal Degradation | Seals melt, crack, leak | Special FFKM, PTFE, metal bellows | 10x longer life in furnace |
| Lubricant Fails | Oil burns or thickens, actuator seizes | Synthetic grease, internal heaters | Runs smooth at -50°C |
| Materials Crack | Metal or plastic parts snap | 304L steel, Inconel, smart composites | No cracks at -196°C |
| Electronics Fail | Chips and wires break in heat | Heat sinks, insulation, remote electronics | Zero signal lost in desert |
How To Pick the Best Actuator for Hot or Cold Jobs
Let’s keep it easy. Here are five big things you must check:
- What is the real temperature?
Is it always hot or cold? Or does it change a lot, like a thermal cycling system?
- What type of actuator do you need?
- Pneumatic actuators: Use air, good for dusty hot spots and some cold jobs.
- Hydraulic actuators: Use oil, strong but the oil can break down in heat or freeze in the cold.
- Electric actuators: Need good thermal management for high or low.
You may want to see our Electric Linear Actuators for smart, safe motion.
- What materials are in the actuator?
- Housing, shaft, piston, gears—what are they made from?
- Match them to your temperature. In the cold, use stainless steel. In the heat, superalloys rock.
- How are the seals made?
- If you need special gaskets or O-rings, pick from our big list. Metal bellows for super hot, PTFE seals for super cold.
- Power source and safety
- Is your power steady and safe?
- For dangerous spots, check IP rating or ATEX certification.
Cool Real-Life Examples
High Temperature Work
- Glass factory furnaces: Need heavy-duty, high temperature actuators for dampers.
- Oil & gas rigs: Actuators on downhole tools see big heat and pressure.
- Power plants: Steam valves must stand up to hot and wet for many years.
Cryogenic/Cold Applications
- LNG plants and storage: Very cold. Standard seals freeze—use our custom cryogenic actuators.
- Refrigerated warehouses and trucks: Automation must always work, even at -50°C.
