About Mini Boiler

Gyantosh's Mini / Small Industrial Steam Boilers are compact, shop-assembled, skid-mounted packages built for industries with modest steam requirements. Fully factory-assembled and tested before dispatch, they arrive ready to connect — minimising site work, civil cost, and installation time.

Despite their small footprint, mini boilers are built to the same engineering standards as larger units: certified boiler-quality pressure parts, a robust shell-and-tube design, and reliable combustion for steady steam supply. They are the ideal entry-level steam solution for small workshops, laboratories, laundries, small food and pharma units, and pilot processes.

Every mini boiler is designed and manufactured in compliance with IBR 1950 (mini boilers as defined under the Indian Boiler Regulations), with semi-automatic operation for simple, dependable running by a single operator.

Available from 300 to 1500 kg/hr (0.3–1.5 TPH) at a working pressure of 10.5 kg/cm², GyanTosh mini boilers give smaller industries a cost-effective, compact, and reliable source of process steam. Backed by over two decades of boiler engineering experience.

A mini boiler for steam is specified the way any boiler is — fuel first, then flow and pressure — but the small steam boiler market is shaped by a constraint the larger sizes rarely face: what the site can physically take. Workshops, laboratories, laundries and pilot lines frequently have no fuel yard, no ash route and no corridor for a chimney. The catalogued range above is solid-fuel fired and covers most of that demand. Where a site genuinely cannot accept fuel handling, a mini gas boiler, or an electric boiler small enough to stand beside the process it serves, is built to order against the same certified pressure-part standards — moving the cost from site work to running cost rather than removing it.

Design & Combustion

Shell & Tube Construction

A compact fire-tube shell design gives a large heating surface in a small footprint, with a generous water volume for steady steam supply.

Skid-Mounted Package

The boiler, mountings, and fittings are assembled and tested on a single skid at the factory, so site work is limited to connections and commissioning.

Simple Combustion System

A straightforward solid-fuel combustion arrangement matched to small capacities keeps operation and maintenance simple.

Advantages of a Mini Boiler

Low Capital & Installation Cost

Compact, skid-mounted, and factory-tested — mini boilers minimise civil work, site labour, and installation time, keeping total project cost low.

Fast Commissioning

Arriving fully assembled and tested, the boiler needs only connection and commissioning to be put into service.

Space-Efficient

The small footprint suits plants where floor space is limited or steam demand is modest.

Simple Operation

Semi-automatic control allows a single operator to run the boiler dependably with minimal training.

IBR Compliant

Built to IBR 1950 standards, giving small industries certified, safe steam generation.

Reliable Entry-Level Steam

Same engineering quality as larger boilers, right-sized and priced for smaller steam requirements.

Frequently Asked Questions(7)

What is a mini boiler?
A mini boiler is a compact, shop-assembled, skid-mounted steam boiler built for industries with small steam requirements — typically 300 to 1500 kg/hr. It arrives factory-assembled and tested for fast commissioning.
What capacity and pressure does it offer?
GyanTosh mini boilers are available from 300 to 1500 kg/hr (0.3–1.5 TPH) at a working pressure of 10.5 kg/cm².
Is a mini boiler IBR certified?
Yes. GyanTosh mini boilers are built and certified to IBR 1950 as applicable to mini boilers under the Indian Boiler Regulations.
Why choose a mini boiler over a larger one?
For small or intermittent steam needs, a mini boiler offers much lower capital, civil, and installation cost, a small footprint, and simple operation — right-sized to the demand without over-investment.
What fuels does it use?
GyanTosh mini boilers are commonly coal or solid-fuel fired; wood, briquettes, and selected biomass options are also available.
How quickly can it be installed?
Because it is fully assembled and tested on a skid at the factory, site work is limited to connections and commissioning — installation is typically completed in 1–2 weeks.
Who uses mini boilers?
Small and medium enterprises, laundries, laboratories, small food and pharma units, workshops, and pilot plants use mini boilers for their modest steam requirements.
