Up to 70% lower energy use
In suitable high-variation load profiles, variable-speed operation can significantly reduce unnecessary motor power consumption compared with conventional fixed-speed operation.
Products & Solutions
Marine Equipment & Systems
Marine equipment covering MAN engine spares, VFD and fuel heating, liquid-cargo insulation, liquefied-gas analysis and monitoring, cryogenic valves and vacuum pumps, selected around marine environment, interfaces, certification and lifecycle maintenance.
Energy performance
Turn variable-speed control into measurable operating savings.
VFDs match pump and fan speed to actual demand instead of forcing motors to run continuously at full speed. For vessels with highly variable auxiliary loads, the energy-saving potential can be substantial.
Fast retrofit payback potential
For projects with sufficient operating hours and energy-saving headroom, estimated retrofit payback can be approximately 6–12 months, creating continuing savings thereafter.
Cooling-water and engine-room ventilation are the two core retrofit scenarios.
The solution is tailored for vessel-specific requirements such as coordinated operation of multiple pumps and fans, highly variable operating conditions and high stability requirements, helping maintain reliable operation while improving energy efficiency.
Actual energy savings and payback depend on the vessel load profile, operating hours, electricity/fuel cost, equipment condition and retrofit scope, and are confirmed through project-specific calculation and onboard data.
Solution configuration
Configure the drive package around the vessel, not the other way around.
The final package is defined from onboard survey data, motor loads, control philosophy, interface conditions and class requirements.

Core application solutions
Control strategies for the two highest-value auxiliary systems.
Demand-based flow and pump coordination
- Dynamic regulationAdjust motor speed and the number of online pumps from real operating demand, avoiding unnecessary pumping power.
- Coordinated controlMultiple drives communicate and balance accumulated running hours to reduce long-term loading on individual equipment.
- HMI visibilityDisplay operating status, trends, alarms and adjustable parameters on the HMI for controlled and transparent operation.
Automatic ventilation matched to changing machinery-space demand
- PID controlAutomatically regulate fans from temperature, pressure or differential-pressure feedback to respond precisely to operating changes.
- Bypass protectionProvide bypass or fallback operating modes so ventilation can continue if the variable-speed control path is unavailable.
- Remote integrationRemote control and communication interfaces can be integrated with the vessel central monitoring or automation system.

Project delivery
From onboard survey to verified savings and lifecycle support.
The delivery model can be adapted to vessel schedule, docking window, installation conditions and the owner’s preferred scope of supply.
01
Pre-project communication & onboard survey
Collect vessel parameters, operating conditions and energy demand; inspect installation space and construction constraints; and complete the initial technical and savings assessment.
02
Customised solution design
Use survey data and vessel operating characteristics to define the control strategy, equipment selection, interfaces and expected efficiency improvement for the specific vessel and route profile.
03
Integrated installation & commissioning
Provide an integrated scope covering equipment, engineering, cabling, foundations, installation and commissioning, or supply standardised installation guidance and remote support according to the owner’s preferred delivery model.
04
Energy-performance verification
Use operating and energy data collected by the monitoring system to quantify pre- and post-retrofit performance and verify the achieved energy-saving result against the agreed evaluation method.
05
Lifecycle service support
Eligible equipment is covered by a three-year replacement service rather than repair, excluding damage caused by misuse or force majeure. Scheduled six-month and annual inspection, cleaning, performance testing and system-update services can be provided together with continuous online technical support.
System advantages
Marine electric heating engineered around safety, service life and control accuracy.
From CCS compliance and PLC power regulation to element loading and welding quality, the system is designed for dependable long-term operation onboard.
CCS Compliance Leadership
One of the earliest domestic manufacturers to meet the latest CCS requirements for marine electric-heating equipment.
PLC Grouped Power Control
Grouped PLC control enables stepless power regulation with high accuracy and reduced impact on the onboard electrical network.
Four-Layer Safety Protection
Four coordinated protection layers cover pressure, heater-surface temperature, fuel outlet temperature and sensor-fault shutdown.
Leak-Resistant Welding
A dedicated transition-sleeve and automated welding process strengthens the element-to-flange connection and minimizes leakage risk.
Controlled Annealing Process
A controlled annealing process maintains accurate annealing temperature for stable material performance and service life.
Low Surface Heat Load
Heating elements are selected to a high standard with low surface loading for gentler heating, reduced coking and improved operating safety.
Compact & Serviceable
Compact equipment reduces installation demand while keeping operation straightforward, maintenance accessible and performance reliable.
Customized solution
Controlled fuel heating designed around the vessel — not a one-size-fits-all heater.
We match heating duty, element surface loading, control logic, sensors and protection to the vessel's fuel properties, operating profile, installation space and power conditions. For the shipowner, this means more stable fuel temperature, faster control response, lower routine maintenance demand and easier integration into existing automation systems.

Engineering advantages
Four design details that directly improve safety and service life.
The differences are in the control architecture, protection logic, element loading and manufacturing process — the details that matter most after years of onboard operation.
01
PLC Grouped Control
Heating groups can be switched independently. Any individual group can be taken out of service without stopping the complete heater, extending service life and reducing maintenance cost.
02
Four-Layer Protection
- Heating surface is arranged below the outlet level.
- Outlet pressure sensing allows heating only when pressurized oil flow is present.
- High heating-element surface temperature triggers alarm and shutdown.
- High fuel outlet temperature or sensor fault triggers alarm and shutdown.
03
Heating Element Manufacturing
- Stainless seamless tube material selected to boiler/heater service requirements.
- Magnesium-oxide filling quality is strictly controlled.
- Oil-heating element surface load is kept at ≤2 W/cm² for gentler heating, reduced coking and less fuel degradation.
04
Element Welding Process
- A thicker transition sleeve strengthens the connection between the heating element and flange to reduce leakage risk.
- Automatic welding delivers consistent, clean and reliable weld quality.
