Compressor Control Systems
PRODUCTS
Find the right solution for your compressor.
Across screw, reciprocating, centrifugal, integral gas, and axial compressors, oil temperature is what determines uptime, efficiency, and overhaul costs. There are two technologies worth talking about — pick the one that matches your application?
Electric/Pneumatic Actuated 3-Way Rotary Control Valves
Modulating pneumatic actuation for precise oil temperature control in hazardous-area compressors. Remote sensing, low pressure drop, mixing or diverting. Direct fit for the air supplies you already have on site.
Best for: Screw, Centrifugal

THERMOSTATIC 3-WAY CONTROL VALVES
Self-contained wax element control for stable, predictable loads. No power, no wiring, no signal, just proven mechanical reliability.
Best for: Reciprocating, Integral Gas, Axial

WHY IT MATTERS
Oil temperature is make-or-break.
Across all compressor types, lube oil temperature controls everything — viscosity, moisture, bearing health, and overhaul intervals. There's no margin for "close enough."
Every +10°C increase roughly halves oil life.
A direct consequence of the Arrhenius rate law. Run too cold and condensation destroys bearings. The question isn't whether to control temperature — it's how precisely you can do it.
TOO HOT
Breaks down oil.
Destroys bearings.
OPTIMAL RANGE
Protects components.
Maximizes performance.
TOO COLD
Causes condensation.
Risks corrosion.
WHY IS THIS SOLUTION RIGHT FOR YOU?
Two approaches. One clear upgrade path.
AMOT offers both solutions. Thermostatic wax valves are proven for stable, predictable loads. But if conditions vary — seasonally, by load, or ambient — dynamic electronic control is the smarter long-term investment. It's the difference between reacting to temperature and actually managing it.
THERMOSTATIC WAX
- Responds to internal temp only
- Fixed set point
- Slower response times
- No position feedback or diagnostics
ELECTRIC/PNEUMATIC CONTROL
- External or remote sensing
- Programmable, dynamic set point
- Accurate, responsive control
- Live position + diagnostic feedback
MORE CONTROL PRODUCTS
Found on the same compressor.
AMOT also supplies air, gas, monitoring, and shutdown controls commonly specified alongside our temperature solutions. Most are sold as direct replacements for legacy equipment, or as part of an integrated package.

INDUSTRIES SERVED
Built for the industries that can't afford downtime.
Compressors are mission-critical in some of the world's most demanding environments. Whether you're running a natural gas gathering station, a mine ventilation system, or an offshore platform, AMOT's control solutions are engineered for your conditions — not just the lab.

WHY AMOT
Air. Fuel. Temperature. We control all three.
Since 1948, AMOT has delivered control solutions for the world’s toughest applications—from offshore platforms to mine sites to power generation. Wherever you operate, your solution is built close to those who understand your needs.
One supplier across the whole compressor.
Most vendors specialize in one piece of the puzzle. AMOT engineers and manufactures across all three control fluids that determine how a compressor runs — air, fuel, and temperature. That means fewer vendors to manage, parts that integrate cleanly, and one engineering team that understands the full picture.
