【Conversion evaporation】400~2,000Kg/h
Used fuel:LNG・LPG・Diesel・Kerosine


Standard type
Equipped with a BL controller, basic control can be performed through easy operations.
High quality steam is stably supplied, while high performance and efficiency are achieved.

High-grade type
The S-Navi system controls and manages the boiler.
Steam can be efficiently generated and appropriately controlled.
The high-grade type with the S-Navi system realized a control system that can perform not only boiler control but also its management.

・A high performance control system (with S-Navi) and high efficiency are realized.

・A boiler body having an efficiency of 90% by itself is used.

・A Hybrid structure with excellent durability and heating efficiency has been developed.

Uses a hybrid heat exchange boiler body Hi

・This boiler body has achieved an efficiency of 90% by itself.
We have thoroughly analyzed the convection and heat transfer part of the boiler body.
A high efficiency boiler body, named “hybrid heat exchange boiler body Hi”, was finally developed by properly combining three types of fins and a slit swirl.
In this boiler body, high-speed combustion gas generates an intense swirl among water pipes. This enables effective heating and realizes a self-cleaning function to prevent soot from adhering and accumulating.
This high efficiency boiler body has highly improved heating efficiency, while realizing excellent durability and stability.

・Models equipped with a high efficiency economizer has realized an efficiency of 96%.
