Non-Varnishing Ultra Coolant: Protection That Pays for Itself

Ultra Coolant is engineered for varnish-free operation and actively dissolves deposits left behind by conventional lubricants.

The result:

• Improved heat transfer efficiency

• Lower energy consumption

• Extended separator life

• Enhanced airend reliability

• Reduced maintenance and downtime

With Ultra Coolant, you’re not just lubricating your compressor — you’re protecting its performance, efficiency, and lifespan.

The Hidden Cost of Varnish in Compressors

Varnish buildup is not just a maintenance issue — it directly impacts performance, reliability, and operating costs.

What varnish does to your system:

• Clogs Cooler Tubes
  Reduces heat transfer efficiency, causing higher operating temperatures and increased system stress.

• Damages the Airend
  Obstructs critical bearing oil passages, increasing the risk of premature airend failure.

• Increases Separator Pressure Drop
  Shortens separator life, reduces energy efficiency, and drives up electrical consumption — not to mention added replacement and labor costs.

Varnish silently increases downtime, energy bills, and component replacement frequency.

High Thermal Conductivity. Superior Cooling.

Ultra Coolant is formulated with exceptional thermal conductivity, allowing it to transfer heat away from critical components more effectively.

The result:

• Lower operating temperatures

• Improved energy efficiency

• Extended coolant service life

• More stable performance under high-load conditions

Even in demanding environments, your compressor runs cooler, smoother, and more efficiently.

The Impact of Overheating on Compressor Performance

Excessive operating temperatures do more than raise alarms — they directly reduce efficiency and increase operating costs.

Consequences of overheating:

• Reduced Efficiency
  Higher temperatures force the compressor to work harder, leading to increased power consumption.

• Shortened Coolant Life
  Excess heat accelerates coolant breakdown, resulting in more frequent change intervals and higher maintenance costs.

Over time, overheating compromises both system reliability and your bottom line.

Ultra Coolant: Minimal Carryover, Maximum Efficiency

Ultra Coolant is engineered for exceptionally low carryover, significantly outperforming Diester and PAO-based coolants.

Field-tested benefits:

• Carryover is typically four times lower than hydrocarbon oils

• Reduced top-up requirements

• Less filter maintenance and condensate disposal

• Improved overall system efficiency

With Ultra Coolant, you save on maintenance, reduce waste, and keep your compressor running clean and efficient.

The Hidden Cost of Coolant Carryover

Excessive coolant carryover can quietly drive up costs and maintenance demands.

Problems caused by high carryover:

• Higher Operating Costs
  More frequent top-ups increase coolant consumption and overall expenses.

• Increased Strain on Filtration Systems
  Inline filters face a heavier load, while excess oil in condensate requires disposal — adding time and cost.

Ultra Coolant: Superior Hydrolytic Stability

Ultra Coolant is engineered for excellent hydrolytic stability, outperforming Diester-based coolants.

Benefits:

• Highly resistant to breakdown from water contamination

• Reduces varnish formation

• Maintains optimal lubricating efficiency

• Extends compressor life and reliability

  Low Hydrolytic Stability: A Silent Threat

  Coolants with poor hydrolytic stability can compromise your compressor’s performance and longevity.

  Risks of low hydrolytic stability (e.g., Diester-based coolants):

  • Increased Varnish Formation
    Coolant breakdown leads to deposits that reduce system efficiency and reliability.

  • Reduced Compressor Life
    Degraded coolant loses its lubricating properties, accelerating wear on critical components.

Ultra Coolant: High Viscosity Index for Maximum Protection

Ultra Coolant features a high Viscosity Index (VI), meaning its viscosity changes minimally with temperature fluctuations.

Key benefits:

• Optimized sealing and lubrication

• Reduced wear on bearings and moving parts

• Greater energy efficiency

• Longer compressor lifespan

Stable Viscosity: Essential for Reliable Compressor Performance

Viscosity is critical for both lubrication and sealing efficiency in rotary screw compressors. When operating temperatures rise, low-stability coolants thin out, reducing their effectiveness.

Why viscosity stability matters:

• Maintains Lubrication Efficiency
  Ensures moving parts are properly lubricated, reducing wear and extending component life.

• Prevents Gas Leaks
  Stable viscosity helps maintain tight sealing, preventing efficiency losses.

• Supports Long-Term Reliability
  Consistent viscosity protects bearings and critical components, extending overall compressor life.

Ultra Coolant: Higher Efficiency, Cleaner Operation

Ultra Coolant is Poly-Glycol-based, engineered for optimal compressor performance:

• Operates cooler, even under high load

• Prevents varnish and deposit formation

• Reduces carryover, lowering maintenance and coolant consumption

• Improves overall energy efficiency and system reliability

Ultra Coolant vs. Polyalphaolefin (PAO)

Polyalphaolefin (PAO) Coolants

Composition: Synthesized hydrocarbons (similar to mineral oils)

Advantages:

• Compatible with most elastomers

• Good viscosity stability, longer life than conventional mineral oils

Disadvantages:

• Prone to carbon formation and varnish buildup

• Limited cooling performance for rotary compressors

• High carryover, increasing top-ups and filter load
