Choosing a Poultry Equipment Supplier: Questions to Ask Before Buying
Poultry house equipment runs for many years, and its performance affects the flock every day. An exhaust fan that fails in the summer heat, a leaking water line or a controller whose parts cannot be found costs far more than the difference in purchase price. For this reason, choosing the supplier matters as much as choosing the equipment itself.
This article is a checklist of questions to ask every supplier before signing a contract for house equipment, with the answers obtained in writing. Comparing offers is only fair when all sellers have answered the same questions.
Why price alone is not a basis for comparison
Two offers with the same title (“complete house fit-out” or “12 × 140 exhaust fans”) may have completely different content: one includes installation and commissioning and the other does not; one states fan capacity at the house’s operating pressure and the other in free air; one has spare parts in stock and the other places a foreign order for every part. Until the scope of work, technical specifications and after-sales commitments are aligned, comparing the final figure is misleading.
Checklist 1: technical specifications and datasheets
- Is a technical datasheet or official catalogue provided for every item? Model, dimensions, material, motor power, capacity and measurement conditions should be in writing.
- At what pressure is the fan capacity stated? The Cobb guide stresses that the capacity of tunnel fans should be stated at a static pressure of at least 25 pascals. Capacity stated at zero pressure is of no use for house design. Cobb also mentions indicators such as energy efficiency (airflow per watt) and the airflow ratio at higher pressures for evaluating a fan.
- Have the specifications been matched to the house’s calculated requirement? A good offer derives the number and capacity from the house dimensions, number of birds and climate, and shows this calculation.
- What are the brand and country of manufacture of the main components (motor, gearbox, nipple, controller)? These should be comparable across offers.
- Is the installation and operation manual supplied in a usable language? Manuals from reputable manufacturers include installation spacing, a lubrication schedule and load limits, and the house team needs them for maintenance.
Checklist 2: written warranty
- Exactly which parts does the warranty cover, and for how long? “It has a warranty” is not enough; the motor, body, impeller, controller electronics and consumable parts may have different terms.
- From what date does the warranty start? Invoice date, delivery or commissioning.
- What voids the warranty? For example, installation by someone other than the seller’s installer, power fluctuations, hard water or the use of particular cleaning agents.
- What is the warranty claim procedure? Who pays for travel, dismantling and transporting the part, and how quickly is replacement or repair carried out?
- Are all these points included in the contract text or a signed warranty sheet? A verbal promise cannot be pursued in a later dispute.
Checklist 3: after-sales service and spare parts
- Are consumable and frequently failing parts (belts, bearings, nipple pins, pressure regulators, sensors, relays) in stock?
- What is the response time for breakdowns during a rearing cycle? A fan or water line failure in the middle of a cycle cannot wait.
- Is telephone support, or sending a specialist to the site’s city, possible?
- Is the house team trained to operate the controller and carry out routine maintenance?
- If a part is discontinued, is there a compatible replacement? Especially for the controller and electronic parts.
Checklist 4: installation and commissioning
- Is installation part of the contract or separate? Exactly what does the installation scope include: wiring, water and gas piping, connection to the controller, adjusting line heights?
- Who is responsible for coordination with the shed builder? The locations of inlets, exhaust fans, pads and winch supports must be settled before the structure is closed; poor coordination between the shed builder and the equipment installer can lead to rework.
- What does the handover (commissioning) test include? It is advisable for the list of tests to be included in the contract: operation of all exhaust fans and opening and closing of shutters, a house pressure test, heaters switching on from the controller, nipple flow, the feed line running to the end of the line, alarms, and emergency power. Ross considers a backup power system and a power-failure alarm necessary and recommends regular testing at full capacity.
- What documents are handed over on delivery? The as-built layout drawing, the controller’s initial settings, manuals and warranty sheets.
Checklist 5: delivery time and payment terms
- What is the delivery time for each item, and what does it depend on? Imported or custom-built items may take time.
- What consequences does the contract set for late delivery or installation? The chick placement schedule depends on the delivery date.
- To which stages is payment tied? Part of the amount is best tied to delivery and a successful commissioning test.
- Until what date are the price and offer valid, and who is responsible for transport and cargo insurance?
Checklist 6: a verifiable track record
- Is it possible to visit a completed house? Seeing equipment after one or more cycles of operation provides information a catalogue does not: the condition of impellers and shutters, water line leaks, line levelling and the tidiness of the wiring.
- Can the operator of that house be consulted? About the speed of response to breakdowns and the supply of parts.
- Is the published work verifiable? Photos and descriptions should specify the location, house type and scope of work.
Documents that should be attached to the contract
The answers to the questions above are only of value when recorded in the contract documents. It is advisable for the following documents to be attached to the purchase contract:
- A list of items with model and quantity: the same list used as the basis for comparison, not a general title.
- Technical datasheets or catalogues for each item: with measurement conditions (for example, operating pressure for exhaust fans).
- The proposed layout drawing: locations of exhaust fans, inlets, heaters, feed and water lines and the controller.
- A description of the installation scope and the handover test list: what the seller does and what is the buyer’s responsibility (for example, power supply up to the panel or gas piping up to the house inlet).
- A signed warranty sheet: with the covered parts, duration, start date and voiding conditions.
- A delivery and installation schedule: with the payment stages tied to it.
If parts of the equipment are bought from several different sellers, responsibility for coordination and integrated testing of the house (especially connecting exhaust fans, heaters and inlets to one controller) must be explicitly assigned to one party; otherwise, at every breakdown each seller will blame the other.
Warning signs
- No written technical specifications are provided, or only a “maximum” figure is given without measurement conditions.
- The warranty is only verbal, or its terms are unclear.
- The installation and commissioning scope in the offer is vague.
- The offer is made without asking about house dimensions, number of birds and climate.
- No completed installation can be visited.
- General claims such as “the best” or “the only” are made without evidence.

Frequently asked questions
What is the most important question before buying poultry equipment?
Exactly what the scope of work is: which items with which specifications, whether installation, commissioning and a handover test are included, and what the warranty covers. Without these, comparing prices is meaningless.
Why should fan capacity be stated at a specific pressure?
Because a fan’s airflow falls as house pressure rises. Cobb recommends stating the capacity of tunnel fans at a pressure of at least 25 pascals.
Is it necessary to visit a completed installation?
A visit shows what condition the equipment is in after a period of operation and how the supplier provides support in practice; information a catalogue does not give.
What should be checked in the house handover test?
Operation of exhaust fans and shutters, house pressure, heaters from the controller, nipple flow, the feed line, alarms and emergency power. Ross recommends regular testing of backup power at full capacity.
