Questions are great.

Rex is Ratermann's AI product expert, a knowledgeable assistant trained on Ratermann's full product catalog and built on decades of real-world compressed gas and cryogenic industry experience. Rex doesn't just reference a database — it taps into the internal knowledge of Ratermann's own team, drawing on 30+ years of hands-on field expertise that our team members have accumulated and refined over their careers.

Think of Rex as a confident guide — like having a Ratermann Rep in your pocket — who's here to help you find the right parts, understand your options, and navigate Ratermann's catalog with the kind of informed perspective you'd expect. And when you need to go deeper, Rex connects you directly with Ratermann's team.

Rex collects your contact information so we can protect the conversation if the connection drops, send you product specs or quotes if needed, and make sure Ratermann's team can follow up effectively. Your information is used purely for continuity and service purposes.

Rex will ask for all three — name, email, and phone number — once, in a single request.

General-purpose AI assistants like ChatGPT or Claude are built on broad, generic large language models (LLMs) trained across billions of data points pulled from the open internet — designed to answer almost anything, which means they're optimized for nothing specific. When you ask them about a compressed gas fitting or a cryogenic valve, they're making their best guess from a generalized training set that has no real grounding in our industry.

Rex is different at the architecture level. Rather than querying a generic LLM, Rex has been purpose-built and trained exclusively on Ratermann's own knowledge infrastructure — a curated, proprietary data foundation that represents over 30 years of hands-on expertise in the compressed gas and cryogenic industry. That institutional knowledge, accumulated by our team across decades of real-world application, has been systematically engineered into Rex's core.

That means when Rex identifies a part, compares two products, or surfaces a spec, it's not interpolating from a broad public dataset. It's working directly from Ratermann's actual inventory data, approved product documentation, and field-tested knowledge — none of which exists in any public LLM.

Rex is also integrated with Ratermann's team. When a question exceeds Rex's scope, it escalates to a real person — not another bot, not a generic fallback. That combination of a deeply specialized knowledge base and direct human connection is what fundamentally separates Rex from anything a general-purpose AI assistant can offer.

Rex specializes in Ratermann's product catalog and the compressed gas and cryogenic industry. Rex can help you:

• Find or identify a part by number, description, or photo
• Understand product specs, certifications, and application fit
• Compare similar products neutrally so you can make an informed choice
• Identify your account manager or locate customer service hours
• Determine whether a part is available or needs to be sourced through Ratermann's team

The more context you can bring, the better Rex can help. Useful details include:

• Part numbers (if you have them)
• Model numbers for the equipment involved
• A description of the issue or application
• Photos of the part, damage, labels, or surrounding area — 3 to 5 images go a long way toward accurate identification

You can upload photos directly to the chat using the paperclip icon.

Rex does not provide direct pricing quotes or process orders. For pricing, lead times, or order placement, Rex will connect you with Ratermann's team — either via live chat during business hours or by phone at 1-800-264-7793.

Rex will never ask for payment information. All transactions go through Ratermann's secure systems.

Yes — and Rex will often ask for them. Where other identification methods can take a day or more, Rex can analyze a photo and identify a part within seconds. When you're diagnosing an unknown component, describing damage, or tracking down a replacement, 3 to 5 clear photos make a significant difference in accuracy.

Helpful shots include:

• Any visible part numbers, stamps, or markings
• A full view of the part alongside a close-up of wear or damage
• The surrounding installation area for context
• A reference object for scale if size is a factor

Use the paperclip icon in the chat to attach images directly.

If you're on a job site, working hands-free, or in the middle of a fast-moving situation where stopping to type isn't realistic, Rex's voice assistant capability has you covered. Simply speak your question — describe the part, the problem, or the application — and Rex will process it in real time and respond just as it would to a typed or photo-based inquiry.

In the field, not every situation allows you to pull out a phone and type. Rex is built with that reality in mind, giving you accurate, catalog-grounded answers whether you're hands-on with equipment or managing a time-sensitive repair — no typing, no waiting, no disruption to your workflow.

Rex prioritizes urgent situations. If you're dealing with active downtime, a time-sensitive repair, or a high-stakes decision, Rex works to gather the right details quickly and — when appropriate — offers to connect you directly with a live Ratermann representative.

During business hours (Monday–Friday, 8 AM–8 PM EST), a live team member can be reached via chat or at 1-800-264-7793.

Never. Rex will not ask for credit card numbers, banking details, or any payment credentials. All payments go directly through Ratermann's secure systems. If Rex is ever asked to collect payment information, it will decline and redirect you appropriately.

Rex is trained on Ratermann's full product catalog and continuously improving — but like any AI, it's not infallible. Always confirm part accuracy with a Ratermann team member before placing an order.

Rex will never fabricate part numbers, availability, or compatibility. If it's unsure, it will say so and connect you with the team rather than guess.

Live support is available Monday through Friday, 8:00 AM–8:00 PM EST. During those hours, Rex can connect you to a live representative via in-chat escalation. Outside of those hours, Rex can still help with product questions.

Rex will always tell you when something is outside its scope, and it will never guess or fabricate an answer. For questions about payment terms, order status, refunds, or anything beyond the product catalog, Rex will direct you to Ratermann's team at 1-800-264-7793.

Just ask Rex. It will look up your account manager using your contact information and state. If it can find a match in the database, it will provide the details directly. If not, it will point you to Ratermann at 1-800-264-7793 for a definitive answer.
