KOSUN Mud Cooling System : General Purpose vs. Offshore Dedicated Models

Mar 20, 2026

In the fields of deep, ultra-deep, and HPHT (high-pressure, high-temperature) well drilling, bottom-hole temperatures often exceed 200°C. High-temperature drilling fluids not only shorten the lifespan of drill bits but also pose significant threats to operational safety. To address this challenge, Xi’ an KOSUN has developed two core mud cooling systems specifically designed for the extreme conditions of both onshore and offshore environments.
 
Onshore General Purpose: The "Energy-Saving Champion" for Extreme Terrains
The general-purpose system (such as the KSNQ-150) is specifically designed for arid, water-scarce, permafrost, or deep-well environments. Utilizing a closed-loop cooling method with specialized finned heat exchange tubes, it boosts efficiency by 10%, achieving a temperature reduction of 20–40°C. The core of this system lies in its intelligent self-control: the system automatically activates evaporation mode when the dry-running mode is insufficient for cooling. This design significantly minimizes water evaporation—making it ideal for deserts and water-scarce regions—while the unique piping arrangement provides excellent anti-freezing and anti-scaling capabilities.
 
Offshore Dedicated Model: The "Space Master" for Marine Platforms
Deck space on offshore drilling platforms is at a premium. The KOSUN offshore dedicated model (KSNQ-150.1) has undergone a structural revolution:
Compact Structure: By utilizing a high-efficiency plate heat exchanger, the footprint has been dramatically reduced from 15 m² to just 5 m² for the same processing capacity.
Powerful Heat Exchange: It supports two-stage heat exchange, achieving a maximum temperature reduction of up to 50°C.
Extreme Corrosion Resistance: The core components are made of specialized materials with superior resistance to sea salt and corrosion, ensuring durability against harsh salt spray.
Real-time Monitoring: An all-intelligent control system provides real-time data collection of pressure, flow rate, and temperature.
 
Whether facing the arid conditions of onshore deserts or the space-constrained, high-salinity offshore environments, KOSUN Environmental provides customized solutions to achieve precise temperature control of drilling fluids. The power of technology makes energy extraction more efficient and secure.
