The technical requirements section of a defense and security procurement has to capture both the clinical requirement behind the cooling protocol and the operational constraints specific to a military context. This guide walks through, clause by clause, how to write that section.

Short answer: technical requirements for a defense cooling equipment procurement should add operational criteria beyond standard clinical requirements: structural stability on unprepared ground, reinforced environmental resistance, and compatibility with tactical air transport.

For the full method of preparing the procurement (scoping, defense procedure, evaluation), see our guide on defense and security procurement for emergency cooling equipment. This document focuses specifically on writing the technical requirements themselves.

Standard structure for technical requirements

  1. Context of use and operational scenarios
  2. Clinical and functional requirements
  3. Operational requirements (environment, transport, autonomy)
  4. Demonstration terms under representative conditions
  5. In-service support logistics

Context of use and operational scenarios

"This procurement covers the supply of a cold water immersion cooling system for use at garrison, during scheduled exercises, and, where applicable, in deployed operations. The bidder shall specify how the proposed solution fits each of these use scenarios."

Clinical and functional requirements

"The equipment must allow whole-body immersion consistent with the 'Cool First, Transport Second' protocol (ACSM, IOC, Korey Stringer Institute), with continuous patient access during immersion: airway monitoring, temperature checks, and resuscitation."

Operational requirements

This is the section that sets a defense specification apart from a civilian one:

"The equipment must remain stable and level on unprepared ground across all support points, including under operational stress, with capacity for two people in simultaneous immersion. The structure must withstand degraded environmental conditions (sand, dust, transport impact, wide temperature swings, prolonged UV exposure)."

"Folded weight and volume must be compatible with tactical air transport constraints and/or integration into the unit's collective load-out. The bidder shall specify these characteristics precisely."

"The equipment must be operable without electrical power or fixed infrastructure."

Demonstration terms

"A timed deployment demonstration will be required prior to award, under conditions as close as possible to actual operational use (unprepared ground, transport load representative of the requesting unit)."

In-service support logistics

"The bidder shall specify spare parts lead times, including for deployed configurations, and any first-line maintenance procedures achievable by the end user."

Common drafting mistakes

Kollder One™ and Kollder Go™, built for these requirements

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), meets the transport and deployment constraints of operational contexts.
