PRODUCT OVERVIEW

Staged Electric Heating with Eleven Listed Power Levels.

CLDR uses electric heating elements, circulation control and a digital controller in a compact packaged arrangement. It is suited to projects that prioritize local zero-combustion emissions, quiet operation and straightforward plant-room integration.

The selected model must be checked against the building or process heat balance, electrical transformer capacity, distribution system, circulation flow and destination electrical rules.

WORKING PRINCIPLE

Electrical Energy Is Staged into the Circulating Water Loop.

Treated water circulates through the boiler and external load. The controller stages the electric heating groups according to outlet-water temperature and load demand.

Protection logic monitors water availability, temperature, circulation and electrical conditions. Final sensors, interlocks, pumps and redundancy follow the approved electrical and hydraulic design.

Selection boundaryUse the listed values for initial engineering only. The final approved proposal and drawings define the supplied equipment and performance boundary.
01Power ReviewConfirm voltage, frequency, transformer and available capacity.
02Water CirculationThe selected pump maintains the design flow through the boiler.
03Staged HeatingElectric elements are loaded in steps to match demand.
04Temperature ControlOutlet and return temperatures are monitored by the controller.
05Heat DeliveryHeated water supplies the approved heating or process circuit.

Selection: Confirm the real heat or steam load, operating profile, utility conditions and destination requirements before selecting a model.

Performance: Actual consumption and efficiency depend on delivered energy quality, load, temperatures, tuning, system losses, maintenance and the agreed test boundary.

PROJECT ENGINEERING

Confirm Electrical Capacity and Hydraulic Conditions Before Model Selection.

A reliable proposal starts with measured or calculated project data rather than only a nominal model name.

FREQUENTLY ASKED QUESTIONS

CLDR Electric Hot Water Boiler FAQ.

Does CLDR produce local combustion emissions?

No fuel is burned in the boiler. Project environmental impact still depends on the electricity source and local rules.

Can 24–1,440 kW be selected directly from building area?

No. Select from a heat-loss or process heat-balance calculation, temperatures, operating profile and system losses.

Is 380 V suitable for every destination?

No. The listed range uses a 380 V / 50 Hz basis. The destination electrical standard and transformer capacity must be confirmed.

Does the boiler include circulation pumps?

The final pump quantity and duty are defined in the approved project scope.

Can CLDR connect to a closed circuit?

A closed or separated circuit can be engineered after pressure, expansion, safety and local-code requirements are confirmed.

What data is needed for a proposal?

Send heat load, temperatures, flow, system pressure, power supply, water quality, operating hours and destination.
