CWNS series low nitrogen gas hot water boiler, the use of
horizontal wet three return back float furnace structure,
combustion chamber adopts corrugated furnace, and a low
arrangement, and maximize the increase of radiation heating
surface, all of the flue gas channel under the water, the tail is
equipped with a waste heat water tank, and perfect insulation
outsourcing design, boiler thermal efficiency is above 95%, the
smoke temperature 50 ℃ (general boiler thermal efficiency is 86%,
the smoke temperature 170 ℃).The product design is novel, the
structure is reasonable, the craft performance is good, the safety
is reliable, at the same time has the occupation area small, saves
the energy, the environmental protection performance is good
characteristic.
The design adopts high quality brand burners, valve accessories are
selected imported or domestic products, the boiler can implement
automatic regulation of load, pressure, water level, and has water
shortage, overpressure, flameout, dry burning temperature control
and other multiple automatic protection functions, with high safety
and reliability.This product leaves the factory after being tested
and qualified, it is the ideal heating equipment for industrial and
mining enterprises, service industry and other users.We will strive
to provide first-class after-sales service to ensure the safety and
economic use of users.

Boiler performance advantage
1. Advanced: it adopts durable American and advanced energy-saving
technology from Japan for long life design.
2. Energy saving: A real three-return structure, with a two-return
waste heat tank set at the end to use heat, with a thermal
efficiency of over 95%.
3. Durability: the boiler is made of special boiler plate, flange
connection, imported accessories, uniform heating.
4. Environmental protection: nitrogen oxide emissions are lower
than the national standard for a region.
Safety: strictly in accordance with the Atmospheric pressure hot
water boiler Safety Technical Supervision Regulations.Unique
anti-dry burning temperature control device with one more
protection.
Convenience: automatic monitoring of all operations, after-sales
service on call
Main Features:
A. Simple and intuitive operation interface
With touch type as the control programming, can at any time display
fan, water pump, oil pump and other operating conditions and flame
stepless change state, with a full range of online help, easy to
operate, suitable for any cultural levels of people.
B. The operation is fully automatic and unmanned
With automatic flame proportional regulation, automatic furnace
purge and flame, wind pressure, oil return pressure automatic
detection functions.In addition, the steam boiler also has
continuous automatic water supply, surface discharge automatic
control and water level low limit, high limit automatic detection
functions.
C. Automatic system start and stop
It has the functions of automatic start and stop setting, time
correction, regular start and stop, multiple priority start and
stop, pre-setting of working day and rest day, automatic judgment
of rest day, etc.
The boiler has the standby function when the pressure is higher and
the self-starting function when the pressure is lower.It has the
function of automatically stopping the furnace when the water level
is too high and releasing water before starting again.
D. High reliability of the system
It has the interlocking protection function of oil pump, water pump
and fan overload, ignition failure, abnormal flameout, fan no wind,
gas leak detection failure, gas leak, gas pressure too low, smoke
temperature and gas pressure, and oil return pressure too high
fault.Have operation password, system debugging password, user
program OEM protection password.In addition, the hot water boiler
also has the interlocking protection function of circulating water
vaporization, circulating water determination, water outlet
temperature exceeding and other faults.
E. Rich extension functions
1. Multiple boilers can be networked, and the number of boilers can
be automatically selected and the load of each boiler can be
allocated without setting the main console.
2. The touch screen has remote monitoring function.
3. Through telephone dial-up network, our company can monitor the
operation of each boiler at any time.
