Leading Manufacturer and Suppliers In India

Therefore, to meet the demand of the customers we design pit type furnace as per the size they required. Also, we design our pit type furnaces from high-quality components as well as deliver them in abundant different specifications.

The working of pit type furnace is used for a variety of heating treatment process. In process industries, these pit types of furnaces can also be used in high-pressure applications with temperatures from 800 to 1200 degrees Celsius. And, these furnaces are designed while bearing in mind working controlled atmospheres with inlets for dispersion as well as the allocation of cracked ammonia, hydrogen, LPG, methanol, argon, nitrogen & other process fluids. Further, these furnaces are often laid in a pit to make most of the space available, as well as charges, can be loaded & unloaded easily.

Frequently Asked Questions (FAQs)

Why would I choose a Pit Type Furnace over a box furnace for my shafts and long rods?
It is because of gravity. When you lay a long shaft horizontally in a box furnace at 1,000°C, it starts to sag under its own weight. Hang it vertically in a pit furnace, and gravity keeps it straight through the entire cycle. For anyone treating precision shafts, rods, or slender tools, that difference shows up directly in your rejection rate.
Yes, and Maharith specifically builds these for ferrous and non-ferrous materials. The retort assembly, either sand-sealed or vacuum-sealed under an inert atmosphere, protects aluminium and other non-ferrous metals from oxidation during heating. You don’t need two separate furnaces for two different material families.
More than people expect. Since the chamber goes below the floor, what is placed above ground is just the lid mechanism and control panel. You’re essentially trading floor space for depth, which works well for facilities where floor area is limited but you have vertical clearance to work with. It’s one of the more practical space decisions you can make.
It’s flexible. Annealing, hardening, tempering, carburising, gas nitriding, carbonitriding, stress relieving, aging, and normalising all run in the same basic pit furnace design. The configuration changes, retort, atmosphere inlets, and temperature range, but the core machine handles multiple processes, which matters if your production mix changes over time.
You can run both in Maharith’s pit furnace. The design includes inlets specifically for controlled atmospheres, cracked ammonia, hydrogen, LPG, methanol, argon, and nitrogen. Gas nitriding and gas carburising both work in this setup. Whether you need a retort depends on the process and atmosphere sensitivity, which Maharith’s team will confirm during configuration.
This is where Maharith’s approach stands out. The chamber is designed around your actual component dimensions, not the other way around. If your largest piece is a 2.5 metre shaft and your smallest batch is a set of small dies, that range is factored into the design. You’re not squeezing oversized parts into a standard chamber.
It’s a legitimate concern and one that’s directly addressed in the design. Temperature stratification, where the top of the chamber runs hotter than the bottom, is controlled through zone heating and circulation. The control system monitors the full chamber depth, not just one point, which is what makes treatment consistent across the full length of a long component.
Yes. Maharith’s pit furnaces are specifically designed for high-pressure process industry applications between 800°C and 1,200°C, with pressure capability from 400mm water column up to 9 bar. Process industry applications like coal tar processing and metal ore separation also fall within this design envelope.
Not always. Maharith builds the Pit Type Furnace to support usage across multiple processes without retorts, where atmosphere control isn’t needed. For normalising, open-air stress relieving, or basic annealing, there’s no retort involved. It’s only when you’re running atmosphere-sensitive processes that the sealed retort comes into play.
Automotive and aerospace are the biggest users of long precision components. Foundry and heavy engineering use it for large castings and fabrications. Tooling and die manufacturers use it for hardening and nitriding. Process industries, petrochemical, ore processing, use the high-pressure variants. It’s a broad machine because the vertical loading design solves a real problem in all of these sectors.
You can contact the specialist directly or use the contact form on the website. When you reach out, come with your component dimensions, the process you’re running, target temperature, and whether you need atmosphere control. That information means the team can respond with something specific to your situation rather than a generic catalogue response.
