The right oil is essential for an Air Screw compressor to work well. The right oil protects your compressor and will prevent it from deteriorating quickly. There are many options for compressor oils, so it is important to understand how to select the best one for your commercial system.

Industrial units that use process systems that are distributed plant-wide typically have either of the two process systems of steam boiler systems or thermic fluid heater systems. Boilers were the standard choice in the past, but currently, thermic fluid heating systems are proving to be a superior solution for many applications by providing enhanced reliability, control, and flexibility.

Thermic fluid system

Heating systems with thermic fluid operate in a closed loop in which the thermic fluid (fluid for heat transfer) circulates. Such continual circulation at a constant supply of temperature offers a heat source that users can access as required.

It is possible to control users individually and vary thermic fluid temperature through secondary control loops. In most systems, the fluid for heat transfer (thermic fluid) stays in liquid form all through the loop. But for some niche applications, there are fluids in the vapor phase available which can profit from latent heat instead of simple heat.

Types of fluids for heat transfer

Thermal systems typically use water-glycol, water, and thermic oil. All these have their pros and cons based on performance needs and operating temperature.

Water-glycol and water

Water is the best fluid for heat transfer but has drawbacks like corrosiveness, presence of contaminants, and featuring boiling point at 100°C while freezing point at 0°C. Adding Glycol enhances boiling point and lowers the freezing point, but heat capacity is reduced.

Thermic oil

They tolerate higher temperatures without boiling or raising system pressure. Mineral oils can touch 315°C while some synthetics help touch 427°C. Thermic oils are less corrosive compared to other types of heating media.

GS Caltex’s Kixx Therm oil 46, a synthetic heat transfer oil is suitable for heat transfer systems requiring an oil having film temperature of 340°C. It’s excellent heat transfer capability helps reducing the fuel consumption and improving process time.

How to find the right thermic fluid

Industry: Select the thermic fluid as per your industry. Some thermic fluids have general use, but most have specific applications.

Compatibility with existing fluid: This is a stage where you are comparing options from various manufacturers to consider your existing thermic fluid and figure out how the new fluid will fit.

Budget: This is a crucial factor while selecting the right thermic fluid. But while selecting the right budget, don’t just consider the up-front cost but weigh in operation efficiency and long-term costs.

Emissions needs and efficiency:If your facility, geographic area, or industry has any efficiency needs or other regulations, these must be considered.

In sum, the factors mentioned above in the guide for selecting thermic fluid will help you narrow down your options and find the best thermic fluid for your plant and process. They will help in doing this efficiently and quickly.
