Product Advantages

Reinforced Steel Structure for Generator Installation

The 20HQ Generator Container is designed as a customized steel enclosure for generator sets and related equipment.

A reinforced frame structure provides a stable base for equipment installation, while different structural steel options can be selected according to the approved design and project requirements.

Available steel materials include:

● Corten Steel

● Q235B

● Q355B

The structural arrangement can be adapted according to equipment dimensions, weight distribution and installation requirements.

20HQ Configuration with Customized Internal Layout

With an external dimension of 6058 × 2438 × 2896 mm, the container provides a compact 20HQ-sized enclosure for generator equipment.

Rather than using a fixed internal arrangement, the internal dimensions and equipment layout can be developed according to the generator set and associated components specified by the customer.

This makes the container suitable for projects requiring a purpose-built equipment enclosure rather than a standard shipping container.

Anti-Corrosion Coating System

For projects requiring enhanced corrosion protection, the steel surface can undergo Sa2.5 abrasive blasting before painting.

The available coating system includes:

● Zinc-rich epoxy primer

● Epoxy intermediate coat

● Polyurethane top coat

Paint thickness and coating adhesion can be inspected according to the agreed quality requirements.

The coating system helps protect the steel structure during transportation, outdoor storage and operation in demanding environments.

Flexible Project-Specific Customization

The 20HQ Generator Container can be manufactured according to customer drawings, equipment specifications and project requirements.

Customization options can include:

● Container dimensions

● Steel material

● Internal equipment layout

● Doors and access arrangements

● Electrical system requirements

● Thermal insulation

● Sound insulation

● Shelving

● Exterior color

● Customer logo

● Other project-specific accessories

This allows the container structure and internal configuration to be developed around the actual generator equipment rather than adapting the equipment to a fixed container design.

Application

The 20HQ Generator Container is mainly used as a customized enclosure for generator sets and associated power-generation equipment.

Containerized Generator Systems

The container can house generator equipment within a purpose-built steel enclosure, allowing the generator and related components to be arranged according to the project layout.

Industrial Power Equipment

It can be customized for industrial projects requiring generator sets or other power-related equipment to be installed inside a protected steel structure.

Modular Power Equipment Projects

For projects requiring equipment to be assembled into a modular container configuration before delivery, the 20HQ structure provides a practical platform for integrating generator-related equipment.

The internal arrangement can be developed according to customer drawings and technical requirements.

Project-Specific Equipment Enclosures

Beyond the basic generator enclosure configuration, the structure can be adapted according to specific equipment dimensions, access requirements, insulation requirements and operating conditions.

For projects involving special transportation, marine environments or specific certification standards, the applicable design and certification requirements should be confirmed during the engineering stage.

FAQ

What is a 20HQ Generator Container?

A 20HQ Generator Container is a customized steel enclosure designed to accommodate generator sets and associated equipment.

The internal structure and equipment arrangement can be developed according to the dimensions and technical requirements of the generator system.

Can the generator container be customized?

Yes.Dimensions, structural materials, internal layout, doors, electrical systems, insulation, shelving, colors and accessories can be customized according to project requirements.

What are the external dimensions?

The standard external dimension for this product is:

6058 × 2438 × 2896 mm

The internal dimensions are determined according to the customized design.

What steel materials are available?

Available materials include:

● Corten Steel

● Q235B

● Q355B

The appropriate steel grade should be selected according to the structural design and project requirements.

Can sound insulation be added?

Yes. Sound insulation is available as an optional configuration.

The exact insulation arrangement should be confirmed according to the generator equipment and customer requirements.

Is thermal insulation available?
