Zeus 24V 4kW Low Turn On (LTO) 3.15 Alternator with Isolated Ground

The ARCO Zeus 24v 4kW LTO alternator turns on at lower RPMs, runs cooler, and provides more power than older designs that are larger and heavier. This alternator continuously generates over 1.4kW (51 Amps) at just under 1,500 RPM and almost 2.4kW (87 Amps) at 2,000 Alternator RPM. Put in real-world terms, a marine diesel engine idling at 750 RPM with a 2:1 pulley ratio is generating over 1.5kW (55 Amps), and a Mercedes Sprinter at 750 RPM with a 3.21:1 ratio is generating over 2.5kW (91 Amps)!

The ARCO Zeus 24v 4kW alternator turns on at lower RPMs, runs cooler, and provides more power than older designs that are larger and heavier. The newest generation of 24V performance has arrived.

Competitor’s 24V alternators utilize a 12V rotor and field current which is less efficient and limits output at all RPMs. ARCO utilizes a native 24V rotor and field current. This results in our 24V alternator running cooler than competitor’s 24V alternators, having a direct impact on the alternator lifespan.

Excellent Daily Moisturizer
Size: 8 Ounce
I love CeraVe Moisturizing Cream! It provides long-lasting hydration without feeling greasy or heavy. It works great on both my face and body, leaving my skin soft, smooth, and healthy-looking. The formula is gentle, absorbs well, and is perfect for daily use, even on sensitive skin. Great quality and excellent value for the price. I highly recommend it!”

So Far, Really Good for Dry and Sensitive Skin
Size: 8 Ounce, Size: 8 Ounce
I’ve only been using this moisturizer for about 2 weeks, but so far I really like it. It keeps my skin feeling hydrated throughout the day without feeling greasy or heavy. The texture is smooth, absorbs nicely, and doesn’t irritate my skin at all. I also noticed my skin feels softer and less dry since I started using it. It’s simple, gentle, and works well for everyday use, especially if you have sensitive skin. So far I haven’t experienced any breakouts or strong fragrance issues, which I appreciate. Too early to say long-term results, but my first impression has been very positive and I would buy it again.

Switched from luxury brands and never looked back!
Size: 19 Ounce (Pack of 1)
I used to spend way too much on high end body moisturizers thinking the price meant better results. Tried CeraVe on a whim and realized I was paying for packaging and fragrance this whole time. This does more for my skin than anything I used before. I use it daily all over my body after showering and my skin stays soft the entire day. No irritation ever. The formula is so gentle that I forget I'm even wearing anything. No fragrance, no stinging, no breakouts. Just clean hydration. If you have sensitive skin and you're nervous about trying something new, this is about as safe as it gets. The 19 oz tub lasts a long time even with daily full body use. Ceramides and hyaluronic acid at this price point is honestly ridiculous value. Save your money on the luxury stuff and just get this.

At this rate, I'm leaving this to my kids in my will
Size: 19 Ounce (Pack of 1)
Ten months in and I have barely made a dent in this tub. I am genuinely starting to consider my options — mixing it into smoothies, using it as a cooking fat, applying it to every surface in the house. Something has to be done because at the current rate of consumption this container will outlive me. In all seriousness, the value proposition here is almost absurd. CeraVe Moisturizing Cream is a legitimately great product — dermatologist recommended, ceramides, hyaluronic acid, fragrance free, non-comedogenic, works on face and body, gentle enough for sensitive skin. It does everything a moisturizer should do without irritating your skin or smelling like you bathed in a candle. The 19oz tub is the right call if you actually plan to use moisturizer regularly. A little goes a long way, which is both the best and most frustrating thing about it. Best because you're getting incredible value per ounce. Frustrating because you will be looking at this same tub for the foreseeable future with no end in sight. Great product, generational quantity. Buy it once, pass it down. One star deducted because I now have to figure out what to do with the remaining 18.5 ounces.

It's not glamorous but it works wonders - even while I am on Accutane!
Size: 19 Ounce (Pack of 1)
This is the best, most luxurious lotion I have ever used. And the only lotion that I can even stand to be on my skin. I started Accutane (for acne) last year and was told that my skin would dry out horribly and that I needed to find a good moisturizer to limit the peeling and cracking that I would inevitably experience. Prior to the medicine my skin was oily and very acne prone and every lotion that I had tried either made me feel like I was wearing a latex suit or broke me out horribly. After doing some research I read that this was a great solution and figured I would give it a try. I started it out right away to try to avoid getting dry and was shocked at how well it worked. Even at the beginning when I was still oily this lotion never felt too heavy. Now don't get me wrong-it goes on like frosting and initially feels like a lot-but within minutes it soaks in and leaves your skin feeling like a little kids (not the sticky kind of little kid though-the good clean little kids with undamaged skin). It will last for days too. No need to reapply because it has soaked in to your skin and doesn't just sit on the surface. My skin has never been this soft. And here I am, nearly 9 months in to my Accutane medication regimen and I am not flaking or peeling. In fact, my skin has never looked better or more healthy. My doctors are shocked at how my skin has stayed moisturized because nearly everyone peels. And it doesn't break you out which is obviously something super important. Now, could I be an anomoly? Maybe, but I don't think so. I honestly think this lotion is Just. That. Good! The price isn't bad either!
