Heat Exchanger Mounting

Mounting feet and brackets are critical accessories for securing brazed plate heat exchangers (BPHEs) in heating, cooling, and industrial systems. Mounting feet, typically made of stainless or galvanized steel, are flat or L-shaped supports attached to the BPHE’s base, featuring pre-drilled holes (6–12 mm) for bolting to surfaces. Ranging from 50–150 mm in length and 2–5 mm thick, they support weights of 5–100 kg, ensuring stability and vibration resistance. Ideal for floor installations, they suit applications like HVAC or chillers, withstanding temperatures from -20°C to 150°C.
Mounting brackets, conversely, enable wall or frame attachment, optimizing space in compact setups like heat pumps or refrigeration units. Constructed from durable materials like AISI 316 stainless steel, they measure 100–300 mm long and 3–6 mm thick, with slots or holes (8–14 mm) for fastening. Supporting loads up to 150 kg, brackets offer flexibility—vertical, horizontal, or adjustable orientations—while resisting corrosion and thermal stress (-20°C to 180°C). Both components are tailored to BPHE dimensions and plate counts, ensuring alignment with piping and operational efficiency. Specifications vary by manufacturer (e.g., Alfa Laval, SWEP), often meeting ASME or ISO standards, making them essential for secure, long-lasting installations.

Description

Heat Exchanger Mounting feet and mounting brackets are essential accessories used to secure and install brazed plate heat exchangers (BPHEs) in various systems, such as HVAC, refrigeration, or industrial heating/cooling setups. These components ensure proper positioning, stability, and ease of integration into piping systems. Below is a description of each:

Heat Exchanger Mounting Feet

  • Purpose:  Mounting feet are typically attached to the bottom of a brazed plate heat exchanger to provide a stable base for floor or surface installation.
  • Design:  They are usually small, flat, or L-shaped metal supports with pre-drilled holes. These holes allow the BPHE to be bolted or screwed onto a surface, such as a platform, equipment skid, or foundation.
  • Material:  Made from durable materials like stainless steel or galvanized steel to resist corrosion and support the weight of the heat exchanger.
  • Functionality:  Mounting feet help distribute the exchanger’s weight evenly, reduce vibration, and prevent movement during operation. They are ideal for standalone or horizontal installations.
  • Applications:  Commonly used in setups where the BPHE needs to remain stationary and aligned with connected piping, such as in industrial chillers or hydronic heating systems.

Heat Exchanger Mounting Brackets

  • Purpose: Mounting brackets are used to attach the BPHE to a wall, frame, or other vertical/horizontal structures, offering flexibility in placement.
  • Design: Brackets can vary in shape—often U-shaped, L-shaped, or custom-configured—depending on the exchanger’s size and the installation requirements. They typically feature slots or holes for bolts, screws, or clamps.
  • Material: Like mounting feet, brackets are constructed from robust, corrosion-resistant materials (e.g., stainless steel) to withstand environmental conditions and mechanical stress.
  • Functionality: Brackets allow the BPHE to be suspended or fixed in tight spaces, saving floor space and enabling vertical or angled installations. They also facilitate easy access for maintenance or replacement.
  • Applications: Frequently used in compact systems, such as refrigeration units, heat pumps, or wall-mounted boiler systems, where space optimization is key.

Mounting brackets are essential Heat Exchanger Accessories designed to simplify the installation and secure placement of brazed plate heat exchangers. Given the compact nature of BPHEs, they are often installed in tight spaces or integrated into larger systems, such as outdoor wood boilers, heat pumps, or refrigeration units. Mounting brackets provide a stable, pre-engineered solution to anchor the exchanger to a surface, eliminating the need for field-fabricated supports that might be less precise or durable.

Design and Construction

Heat Exchanger Mounting brackets are typically constructed from robust materials like stainless steel or heavy-gauge steel to match the durability of the heat exchanger itself. Stainless steel is a common choice due to its resistance to corrosion, especially in environments where moisture or chemicals are present. The brackets are engineered with pre-configured mounting and anchor holes, allowing for quick attachment to the exchanger and the mounting surface. Some designs incorporate threaded studs or bolts protruding from the BPHE’s front cover, which align with corresponding holes in the bracket. This setup enables a straightforward bolt-on installation.

For example, a typical mounting bracket for a 5″x12″ BPHE might feature four mounting studs on the exchanger’s front plate, designed to fit a bracket that can then be screwed or bolted to a wall, floor, or equipment frame. The bracket’s shape often conforms to the exchanger’s rectangular profile, cradling it securely while distributing its weight evenly.

Discussion

Mounting feet serve a similar purpose to mounting brackets but are typically simpler and used for ground or floor installations. They are often supplied as part of the BPHE package or as optional Heat Exchanger Accessories, particularly for larger units or applications requiring a low-profile setup.

Design and Construction

Heat Exchanger Mounting feet are usually small, flat plates or tabs made of stainless steel or galvanized steel, attached directly to the base of the heat exchanger. They feature pre-drilled holes for bolting the unit to a surface. Unlike brackets, which may wrap around the exchanger, mounting feet extend outward from its bottom edge, providing a minimalistic yet effective anchoring solution. For instance, a shell-and-tube BPHE might come with a set of mounting feet welded or bolted to its shell, while a brazed plate model might have feet integrated into its base plate.

In summary, Heat Exchanger mounting feet and brackets are simple yet vital components that enhance the practicality and durability of brazed plate heat exchangers by ensuring secure installation and operational stability.

Installation

Installation and Functionality

Installation is a key advantage of mounting brackets. Without them, installers might resort to fabricating supports from bar or angle materials, a process that can be time-consuming and prone to error. With a bracket, the process is streamlined: the exchanger is bolted to the bracket, and the bracket is affixed to the mounting platform. This simplicity reduces labor costs and ensures consistent alignment, which is critical for maintaining proper fluid flow and avoiding stress on the exchanger’s connections.

In terms of functionality, mounting brackets stabilize the BPHE, preventing movement or vibration that could loosen connections or damage the unit over time. They are particularly useful in vertical installations, common for evaporators and condensers, where the exchanger must remain upright to optimize refrigerant or fluid distribution. Some brackets also include rubber strips or buffers to dampen vibrations, enhancing longevity in dynamic environments like industrial machinery or HVAC systems.

Benefits

  • Ease of Installation:  Pre-drilled holes and standardized designs make setup fast and reliable.

  • Durability:  Stainless steel construction ensures long-term performance in harsh conditions.

  • Versatility:  Brackets can be adapted to various exchanger sizes (e.g., 5″x12″ or 10″x20″) and mounting orientations.
