Defense and Security Procurement: Preparing a Tender for Emergency Cooling Equipment (Military Medical Services)

In deployed operations and during intensive training in hot environments, exertional heat stroke remains a preventable cause of death for military personnel. Equipping a medical unit with a cold water immersion solution follows a distinct procurement logic, defense and security procurement, with operational constraints specific to this sector.

Short answer: a defense procurement specification for cooling equipment should add operational requirements beyond civilian criteria: structural stability on unprepared ground, reinforced environmental resistance (sand, dust, impact), and logistics autonomy without fixed infrastructure (ACSM 2023, IOC/BJSM 2021, Korey Stringer Institute).

What sets defense and security procurement apart

Defense and security procurement typically operates under a distinct regime from standard public procurement, built to accommodate supply security and information protection requirements while still preserving a proportionate competitive process relative to contract value.

For emergency cooling equipment, which involves no classified information, the mechanics usually mirror civilian procurement (a simplified procedure below the formal threshold, a formal tender above it), but the specification must account for additional operational requirements specific to the military context.

Step 1: Scope the need by context of use

Use cases vary significantly by unit:

• A fixed medical post at a garrison or scheduled exercise, with vehicle access
• A deployed system for operations abroad, constrained by air transport volume and logistics footprint
• Equipment mounted on a tactical vehicle, requiring minimal folded bulk
• A first-aid post for a parade or ceremony under high heat conditions

This scoping directly shapes the portability, environmental durability, and logistics footprint criteria in the specification.

Step 2: Define non-negotiable operational requirements

Beyond the clinical criteria common to any purchase of this equipment type (whole-body immersion, continuous patient access, compliance with the "Cool First, Transport Second" protocol), a defense-context specification should also specify:

• Structural stability across all support points, on unprepared ground, including under operational stress, with capacity for two people in simultaneous immersion
• Reinforced environmental resistance: sand, dust, transport impact, extreme temperature swings, prolonged UV exposure
• Folded volume and weight compatible with tactical air transport or integration into individual/collective load-out, depending on use
• Logistics autonomy: functioning without electrical power or fixed infrastructure
• Spare parts availability and traceability, with lead times compatible with deployed operations

Step 3: Choose the appropriate procedure

As with civilian procurement, the estimated contract value determines the route: a simplified procedure below the formal threshold, a formal tender above it. Applicable thresholds are published and revised periodically. Check the current figure before launching the process rather than relying on a figure that may be out of date.

As with any public purchase, using a pre-approved supplier catalog listing a limited pool of vendors remains an option, not an obligation. A direct competitive process, requesting quotes from multiple manufacturers that meet the operational specification, remains fully available and broadens the comparison to the full range of technically compliant solutions.

Step 4: Require a demonstration under representative conditions

A spec sheet is not enough to validate equipment intended for operational use. Require a timed stability and deployment demonstration, ideally under conditions close to actual field use (unprepared ground, representative transport load). It is the only reliable way to confirm equipment will hold within the exertional heat stroke therapeutic window once fielded.

Common mistakes to avoid

• Selecting equipment validated only for civilian use, without verifying its resistance to transport and operational environmental stress
• Underweighting structural stability on uneven ground, when field conditions are rarely ideal
• Failing to require data on spare parts availability under tight timelines
• Limiting the search to already-listed suppliers without checking for newer solutions on the market

Kollder One™ and Kollder Go™, built for operational use

Kollder One™ combines a stable, six-point steel frame with a structure designed for demanding field conditions, plus room for up to 2 people in simultaneous immersion. Kollder Go™, the hybrid backpack/wheeled transport bag (85 x 10 x 10 cm), was designed for transport and rapid deployment in operational contexts, including for deployed units.
