Frequently Asked Questions
What is the difference between LDO and HSD (Diesel) for this boiler?
LDO is a lower-grade fuel compared to HSD and is often more economical for industrial heating. This boiler is specifically designed with a burner that can handle the slightly higher viscosity of LDO.
What is the thermal efficiency of this 500 Kg model?
This model achieves 88% thermal efficiency, which can be pushed to 92%+ with the installation of a compact economizer.
Does LDO require pre-heating like Furnace Oil?
No, LDO typically flows freely at room temperature, so a pre-heater is generally not required, simplifying the system compared to FO boilers.
How does the boiler ensure fuel savings?
By using a high-precision monoblock burner, the boiler maintains a perfect air-to-fuel ratio, preventing unburnt fuel waste.
What is the exact steam output?
The boiler provides a rated capacity of 500 Kg of steam per hour.
Is this boiler IBR or Non-IBR?
We offer the 500 Kg/hr model in both IBR and Non-IBR versions. For many small-scale units, our Non-IBR "Coil Type" is popular due to fewer regulatory requirements.
What is the standard working pressure?
The standard design pressure is 7 Kg/cm² to 10.54 Kg/cm².
What is the advantage of a "Vertical Coil Type" design?
It allows for instant steam generation (within 3–5 minutes) and has a very small footprint, making it ideal for factories with limited space.
What burner brand is used?
We use premium Riello or ELCO burners to ensure reliable ignition and low maintenance.
Is the 500 Kg LDO boiler fully automatic?
Yes. It features a "Push-Button" start with an automatic control panel that manages the firing sequence and water feeding.
How long does it take to get steam from a cold start?
Our coil-type design provides full pressure steam in just 3 to 5 minutes, which is much faster than traditional shell-type boilers.
What safety features are included?
The boiler includes a high-pressure cut-off, flame failure sensor, low water flow switch, and a spring-loaded safety valve.
What is the electrical load for this unit?
The total connected load is approximately 2 HP to 3 HP, covering the burner motor and the high-pressure feedwater pump.
Can it be operated by a non-technical person?
While it is fully automatic, we recommend a basic training session (provided by us) for your operator to handle daily checks and blowdown procedures.
Is this 500 Kg boiler skid-mounted?
Yes, it is a compact, skid-mounted unit. The boiler, pump, and panel come as a single package for easy "Plug-and-Play" installation.
What kind of water treatment is required?
To prevent coil scaling, a Water Softener is mandatory to keep water hardness below 5 ppm.
How do I clean the coil?
The coil can be cleaned through a process called "Descaling" using a chemical pump. We provide the necessary ports and instructions for this procedure.
What is the footprint (space requirement)?
The 500 Kg vertical model is very compact, typically requiring only about 4 feet x 4 feet of floor space (excluding the softener).
Do you provide service support in Ahmedabad?
Yes, our Ahmedabad-based service team provides 24/7 support, genuine spares, and annual maintenance contracts for all LDO fired units.
