Instrumentation
D’HONDT THERMAL POWER SOLUTION can propose sets of instrumentats including those listed below (but not limited too)
- Temperature Transmitter + Thermowell
- Temperature Indicator + Thermowell
- Pressure Transmitter
- Pressure Indicator
- Vibration switch & transmitter VNB001
Adiabatic systems
Depending on atmospheric conditions and required Water outlet Temperature, D’HONDT THERMAL POWER SOLUTIONS can propose 3 different types of adiabatic systems.
Mid way between dry coolers and cooling Towers, these systems allow to reach a water temperature lower than ambient temperature by injecting water into ambient air and by increasing the RH percentage
- 1. Spraying system => 60% RH saturation
- 2. Ecomesh system => 70% RH Saturation
- 3. Fogging system => 85% RH Saturation
Electrical supply
— Cabling
It is possible to supply the following equipment according to customer’s specifications and local rules :
- Cables and cable tray routine sketches
- Power and instrumentation cables
- Power and instrumentation cable trays
- Cable trays supports
- Cable glands
Cabling scope can be realized partially or fully in our workshops
— Junction boxes
Basically supplied as connecting boxes:
Possibility to supply motor protections
— Fan step control cabinet
Installed on each module, this cabinet allows regulation through the control of the water outlet temperature checked live for AC motor-fan
- by starting/stopping groups of fans for AC motor-fan (single speed)
- by adapting the fan speed for EC motor fans fan (variable speed)
This allows the reduction of the Electricity consumption and increases fan life span
This cabinet includes:
- Motor protection,
- Electronic regulator
- inlet/outlet signal (Digital and Analogic) on demand.
It can work completely independantly or can be driven by the customer’s MCC
— Frequency inverters cabinet
Installed on each module or in a cabinet common to various modules, this cabinet controls the Motor-fan speed according to water outlet temperature live checked
This allow to reduce Electricity consumption and to increase fans life span.
This cabinet includes:
- Motor protection,
- Frequency invertor (Brand on demand)
- inlet/outlet signal (Digital and Analogic) on demand.
It can work completely independantly or can be driven by the customer’s MCC
— Complete MCC
We can provide an intercommunicating group of cabinets allowing the whole Air cooler to work in an autonomous way, communicating with the customer’s DCS
This MCC is made of:
- 1 master cabinet interfacing with the customer’s DCS and slave cabinets
- Several slave cabinets (1 per module) relaying the master’s cabinet set-up and running information
— Engineering support
Thanks to its center of expertise and to its 60 years’ experience in the field of Air cooled heat exchangers, D’HONDT THERMAL SOLUTIONS offers its customer a wide range of training and engineering support:
- Technical training sessions on non-API and API air coolers (or « how to learn everything about air cooled heat exchangers »)
- Upstream Engineering support on air coolers:
- Pre-engineering studies
- Specification’s analyse and synthesis
- Supplier’s proposal analys eand synthesis
- Support to specifications editing
- Support during execution phase (supplier’s follow-up,…)
For Engineering support D’HONDT THERMAL SOLUTIONS acts like an impartial consulting company, separated from the equipment sales department
