An LPG LOT System uses Liquid Off-Take (LOT) cylinders to supply liquid LPG to a manifold system. The liquid LPG is taken from the cylinders and then moves through the required gas handling equipment before it is used by the application. Saraswat Engineers Pvt. Ltd. (SEPL) manufactures LPG LOT systems and 450 kg cylinder manifold accessories for industrial and commercial applications.
The system uses parts such as LOT adapters, flexible pigtails, valves, couplings, filters, sight flow indicators and LPG vaporizers. Together, these parts help connect the cylinders and manage LPG flow through the system.
What Does LOT Mean in an LPG System?
LOT stands for Liquid Off-Take. In this setup, LPG is taken from the cylinder in liquid form.
SEPL LOT Adapter is designed to take liquid LPG from LOT cylinders and supply it to the manifold. The company also states that liquid LPG then moves into an LPG vaporizer.
This makes the LOT cylinder, manifold accessories and vaporizer important parts of the complete setup.
How Does an LPG LOT System Work?
The working process can be understood in a few simple stages.
1. LPG is stored in LOT cylinders
The system starts with cylinders fitted for liquid off-take. SEPL provides accessories for LOT as well as large 450 kg cylinder manifold arrangements.
2. The LOT adapter takes LPG from the cylinder
The LOT adapter connects with the LOT cylinder and allows liquid LPG to move towards the manifold. SEPL’s adapter has an inbuilt check valve that allows LPG to flow in one direction.
3. A flexible pigtail connects the cylinder side to the manifold
SEPL’s LOT flexible pigtail is made for cylinders with a liquid off-take valve. It provides a flexible connection between the LPG cylinder and the manifold or related equipment.
4. LPG passes through the manifold system
The manifold brings the required cylinder connections together. Other accessories help manage and check the LPG as it moves through the system.
5. Liquid LPG moves to the vaporizer
SEPL states that liquid LPG from the LOT arrangement moves into an LPG vaporizer. The vaporizer then provides the gas phase required for the connected application.
What Parts Are Used in an LPG LOT System?
A LOT setup is not based on one component. SEPL manufactures a range of manifold accessories for these systems.

Why Is the LOT Adapter Important?
The LOT adapter has a direct role at the cylinder connection.
SEPL designs its LOT adapter for taking liquid LPG from LOT cylinders and supplying it to manifolds. Its built-in check valve permits flow in one direction. SEPL states that this feature also helps avoid LPG loss when cylinders are changed.
The adapter is therefore an important link between the cylinder and the rest of the LOT manifold arrangement.
How Are Cylinders Connected to the Manifold?
SEPL uses LOT flexible pigtails as part of this connection.
The pigtail is a flexible hose made specifically for LPG cylinders that have a liquid off-take valve. SEPL lists a maximum working pressure of 25 kg/cm⊃2; for its LOT flexible pigtail. The company also offers customized lengths to suit different installation needs.
This flexibility helps connect cylinder adapters to the manifold while allowing the system layout to meet project requirements.
Where Does the LPG Vaporizer Fit Into the System?
The vaporizer comes into the process after liquid LPG is taken from the LOT cylinder arrangement.
SEPL states that liquid LPG moves into an LPG vaporizer from the LOT setup. SEPL manufactures Gasmax LPG vaporizers as part of its industrial gas handling range.
This is why LOT systems and LPG vaporizers are closely connected in many SEPL gas handling solutions. The LOT arrangement handles the liquid supply from the cylinders, while the vaporizer handles the next stage required to provide LPG in gas form.
Where Can SEPL LPG LOT Systems Be Used?
SEPL supplies LOT systems and related components for different industrial and commercial needs. Its published applications include industrial, commercial, hotel, food processing, chemical, agricultural, beverage and automobile uses.
SEPL also lists its LPG LOT system for industries such as:
-
Industrial heating and processing
-
Food processing and manufacturing
-
Aerosol manufacturing and packing
-
Clothing and textile
-
Ceramics
-
Energy and steam generation
The exact system arrangement can depend on LPG requirements, cylinder arrangement, manifold accessories and the needs of the project.
What Should Be Checked When Planning a LOT System?
SEPL does not present every LOT system as one fixed setup. The company states that system requirements and components can change according to the application.
Important points include:
-
Number and arrangement of cylinders
-
LPG requirement of the application
-
Required manifold accessories
-
LOT adapter and pigtail requirements
-
Valve and coupling requirements
-
Filter and flow indicator requirements
-
LPG vaporizer requirements
-
Customer-specific system needs
SEPL has an in-house design facility and states that manifold accessories can be designed according to customer requirements.
